Bio

Dr. Parsian K. Mohseni holds B.Eng. and Ph.D. degrees in Engineering Physics from McMaster University, where he conducted graduate research as part of the Centre for Emerging Device Technologies and the Canadian Centre for Electron Microscopy. He carried out postdoctoral research at the Micro and Nanotechnology Laboratory and the Frederick Seitz Materials Research Laboratory at the University of Illinois at Urbana-Champaign. In 2015, Dr. Mohseni joined the Microsystems Engineering Ph.D. Program at RIT as an Assistant Professor.

Dr. Mohseni’s research interests are cross-disciplinary in nature, spanning the fields of solid state physics, optoelectronics, materials characterization, nano-engineering, and physical chemistry. His primary research focus is bottom-up, heteroepitaxial crystal growth of III-V compound semiconductor nanowires on foreign, functional, and flexible substrates via MOCVD. Additionally, he is interested in novel, top-down methods for fabrication of III-V and Si nanostructures using the metal-assisted chemical etching technique. His research aims to establish innovative synthesis paradigms that allow for precise manipulation of material properties at the nanometer scale and enable next-generation device technologies in optoelectronics, photonics, nanoelectronics, and photovoltaic energy conversion.

Dr. Mohseni has received research awards from the Canadian Institute for Photonic Innovations and the Ontario Centres of Excellence, along with Ontario Graduate Scholarships. His work has resulted in over 30 peer-reviewed publications and has been featured in MIT Technology Review, IEEE Spectrum, Compound Semiconductor, and Materials Today, amongst others.

Currently Teaching

MCSE-703
3 Credits
The intent of this course is to provide a comprehensive review of the fundamental concepts of materials science and engineering with applications to nano- and microsystems. Topics include crystallography, diffusion, phase diagrams, fluids, and thermal, elastic, electrical, optical and magnetic properties. This course provides students in the engineering or science fields of nano- and microsystems with the background for future coursework and research in materials engineering and applications.
MCSE-795
1 Credits
In this seminar course students will present their latest research and learn about the research taking place in the program. All Microsystems Ph.D. students enrolled full time are required to attend each semester they are on campus.
PHYS-213
3 Credits
This course provides an introductory survey of elementary quantum physics, as well as basic relativistic dynamics. Topics include the photon, wave-particle duality, deBroglie waves, the Bohr model of the atom, the Schrodinger equation and wave mechanics, quantum description of the hydrogen atom, electron spin, and multi-electron atoms.
