Research opportunities span multiple areas of expertise, including: 

hand with gloves and microscopic imageryThe research and fabrication of nanomaterials promises to revolutionize a number of industries and scientific fields, particularly biomedical devices and stem cell engineering. A major barrier to significant adoption and incorporation of novel nanomaterials is the need to produce these materials in high volume and at low-cost. We research the fabrication of ultrathin nanomembranes and the methods to produce these materials more simply, while retaining their unique properties. Additionally, we use these nanomembranes to create tightly controlled cellular microenvironments for adult stem cells. These microenvironments are used to help study and induce the differentiation of stem cells for potential uses in tissue engineering. Specifically, we are investigating the differentiation of adult adipose-derived stem cells into cells that can create and support the development of vascular networks. Scale-up of these methodologies for future use in tissue engineering will require high volume production of nanomaterials as the differentiation substrate. 

microscopic imageryThe Biomedical Microsystems Laboratory carries out research in MEMs, sensors, medical devices, integrated electronics, physiological monitoring, signal processing, auditory dysfunction, and assistive device technologies.  Collaborating with colleagues in the colleges of Engineering, Science, and Medicine at RIT, the University of Rochester, the University of South Florida, and Rochester General Health Systems, this group has developed new technologies such as implantable micropumps for inner ear drug delivery; hybrid MEMS sensors and actuators integrating classical microelectromechanical systems with direct write microscale 3D print technologies; user guided assistive listening systems for the hearing impaired; non-invasive physiologic sensors; compressed sensing architectures; nanomembrane electromostic actuators; and soldier worn blast dosimetry sensors.   The group receives funding from industrial partners, the Defense Advanced Research Projects Agency (DARPA), the National Institutes of Health (NIH), and the National Science Foundation (NSF).

microscopic imageryThe Nanophotonics Group is developing silicon photonic chips that will revolutionize computing, communication, and sensing systems. Silicon enabled the electronics age with its good electrical properties, high purity, and scalable manufacturability. However, all electronic devices face imposing performance and energy challenges due to the fundamental limits of electrons. In contrast, photons propagate at the speed of light, can carry vast amounts of information (10’s of Tbit/s), and have minimal noise.  By using the same Silicon nanofabrication manufacturing technology used to make all   integrated circuits, the RIT Nanophotonics group is realizing Silicon nanophotonic devices and systems that have high performance and the potential for low cost.  The groups research is focused on several key areas: optical interconnects for chip-to-chip and on-chip low energy communications (lasers, electro-optic modulators, multiplexing techniques); Silicon compatible nonlinear optics (amorphous Silicon, Silicon nanocrystals);  quantum optical computing and communication (photon sources, gates, and detectors); and ultra-sensitive optical sensing. The research has been supported with funding and close collaborations with a wide range of government and commercial entities.

microscopic imagesThe research activities in the Thin Film Electronics group are focused on inorganic thin-film electronics on both silicon and non-silicon platforms.  Research on low-temperature polycrystalline silicon (LTPS) is exploring an alternative method of crystallization using a flash-lamp annealing (FLA) process.  The instrument uses Xenon flash-lamps with an extremely high irradiance to expose samples with pulses in the microsecond timescale, and was acquired by Prof. Denis Cormier in the Industrial & Systems Engineering Department at RIT.  We have most recently demonstrated the ability to form large-grain material with domains that appear to be 10’s of microns in size; the electronic quality of the material is still under investigation.  Thin-film transistors (TFTs) made at RIT using sputter-deposited Indium-Gallium-Zinc-Oxide (IGZO) demonstrate results among the best reported in the literature, with continued efforts focusing on passivation materials for improved device stability and process integration.  Even though there has been limited introduction of IGZO TFTs in display products, this work continues to be relevant and of significant interest to the display industry.  Other metal-oxide semiconductors as well as two-dimensional materials (e.g. MoS2) are of interest for VLSI in addition to applications on alternative substrate materials.

electronic machinery and a layered graphThe conversion of light from the sun into electrical energy is playing a very important role in our current challenge for alternative energy technologies, to reduce our dependence on fossil fuels as well as reduce greenhouse gas emissions. The vision of Dr. Hubbard’s research group is to accelerate scientific breakthroughs in the discovery of materials and structures that will advance the frontier of the conversion of light to electricity. The group’s focus is on new material systems, fabricating them, and demonstrating proof-of-principle of devices that will deliver a major boost to the world’s pursuit of innovative and transformative energy conversion products. Their strategy to make this outcome possible is through nanoscale and/or novel material (a) synthesis, (b) modeling, (c) characterization, and (d) fabrication of energy conversion devices. The team’s expertise lies in vapor phase epitaxy (VPE) of III-V photovoltaic devices and nanostructures, novel photovoltaic structures such as the intermediate band solar cell, photovoltaic characterization as well as simulation and testing. The outcome of their work could advance (1) the state-of-the-art in device efficiency and (2) lower cost for the conversion of light to electrical energy.

imagery of bio roboticsInvestigating and modelling the mechanical properties of materials is important for many applications. The most common technique used for mechanical characterization of materials is called nanoindentation. The currently available tools utilized in order to perform nanoindentation have their limitations in terms of sensitivities of force and displacement or limitations due to the hardware for a broad range of material properties. When it comes to investigation of soft materials, these limitations might be more detrimental. In Multi Agent Bio Robotics Laboratory (MABL), we have been working on development of novel nanoindentation techniques with a multi-probe atomic force microcopy (AFM) system in order to ease the major problems encountered with standard AFM or nanoindentation systems. Tuning forks are used as probes during nanoindentation. For quasi-static nanoindentation experiments, our approach extracts the force information through the displacement of the indenter probe measured by a second probe with ultra-resolution.  For dynamic nanoindentation techniques, a single probe frequency modulation of the indenter tuning fork is used to extract force information.  Thanks to the high quality of resonance (Q factor) of tuning fork probes, force measurements can be performed with a resolution as small as 1.6 pN. The accurate measurements of material properties on soft materials is  used in characterization of microfabricated pillar sensors which can be used in measuring forces on cancer cells for observing cell traction. The technique developed in this research also enables us to use the system as ultra-sensitive force sensor to apply nN scale lateral and vertical loads on microfabricated structures or biological specimens.

Recently the Rochester Institute of Technology has demonstrated the co-integration of CMOS devices and resonant interband tunnel diodes (RITDs).  Our strategy has been to integrate the tunnel diodes following all high temperature steps, but prior to the contact metallization of the CMOS devices.  A recent paper in the Sept. 2003 issue of IEEE Transactions on Electron Devices co-written by our sister group at the Ohio State University found that compared to the performance of bulk RITDs used as a control (with a peak-to-valley current ratio or PVCR of 3.8), the integrated devices exhibited a slight degradation performance (PVCR of 3.4).  We have also published a paper at the University-Government Industry Microelectronics Conference (UGIM 2003) that showed a slight reduction in performance for integrating atop implant regions.  When formally integrated atop CMOS, the PVCR ultimately was found to be 2.8.  Details of this work were presented in Washington, DC at the 2003 ISDRS conference.  We also have recently demonstrated a simple latch-based circuit in the form of a MOnostable BIstable Logic Element (MOBILE) incorporating an integrated FET and RITD.  We believe that the MOBILE serves as a proof of concept, providing a roadmap as to the biasing conditions where the tunnel diode will ultimately be useful with CMOS.

nano-optomechanics imageryOur group is broadly interested in light-matter interactions from the perspective of fundamental science as well as technological applications. Currently we are focused on the interplay of electromagnetic modes of radiation, such as laser light, with nanofabricated components, such as mechanical oscillators and rotors. Our aims are the cooling of macroscopic objects into the quantum regime and to establish the limits to quantum sensing of mechanical displacement, force, and rotation, for example. These investigations are expected to test the foundation of quantum mechanics as well as to yield next generation sensors that circumvent the limits posed by quantum mechanics to their sensitivity. Some of our effort also goes towards investigating other related platforms for quantum technologies such as ultracold atoms and molecules. Our work is fully theoretical, involving mostly analytical calculations, using the techniques of quantum optics and atomic physics, and some medium-scale numerical work. We collaborate closely with experimental groups locally, nationally, as well as internationally. Our program involves researchers at every level, including undergraduate, masters, and doctoral students as well as postdoctoral scholars. Recent funding sources include the Research Corporation for Science Advancement, the Office of Naval Research, and the National Science Foundation.

microscopic imageryInnovative and greener chemical processes are needed in order to address societal grand challenges, which mostly involve conservation of resources. One of such societal grand challenges is future fresh water supply, for example. New water desalination technologies are urgent considering that 98% of water available in our planet is sea water or brackish water. Our research group focuses on the development of next generation chemical processes to address this kind of challenges that are energy-efficient, low-waste, and with low installation and maintenance costs. We identify physicochemical and transport mechanisms specific to different chemical species that can be triggered by carefully designing separation media and operation conditions. Therefore, we start with basic research on phenomena at the molecular scale that we can exploit and potentiate to develop a chemical process. And, then, we move into applied research of materials and operations in order to devise the chemical process per se. Our methods include a combination of experiments and modeling from the molecular to the macro-scale. Current projects include the development of a family of processes driven by the application of low-voltage electric fields for the purposes of water desalination, selective water deionization, advanced waste-water treatment and electrocatalysis. We are also working in a family of processes for the application of gas hydrates in gas storage and transportation, as well as gas separations.
