SURFACE MODIFICATION OF MATERIALS

Surface modification of materials is a key technology for the processing and manufacture of many products which would otherwise be unattainable. By altering the chemical and physical properties of the surface without changing the bulk properties, adhesion to the surface may be greatly improved. RIT students work with a number of surface modification techniques in the Plasma Science Research Laboratory including:


  1. UV photons
  2. vacuum UV (VUV) photons and reactive neutral particles produced downstream from low pressure microwave plasmas
  3. VUV radiation from inert gas excimers formed in high pressure rotating DC arc
  4. reactive neutral gaseous particles
  5. reactive ions.

The research projects typically have been team efforts between RIT's Departments of Chemistry, Physics, and Materials Science and Engineering, and IBM, Endicott Interconnect Technologies in Endicott, New York, and Xerox Corporation in Webster, New York.
