Layered Inorganic Material Research & Development
Layered inorganic materials with unique properties
include graphene and molybdenum disulfide. These materials exhibit
unique electrical and physical properties. Graphene has been called
the holy grail of semiconductor research since it has the potential to replace
silicon in microelectronics. Molybdenum disulfide shares the unique
atomic structure of graphene, but has its own unique set of properties.
Our current research program is aimed at investigating
these unique physical and electrical properties. We have successfully created
transistors using graphene. We have also conducted work on the wettability
of graphene and molybdenum disulfide. There are many applications for
atomically thin coatings that can resist wetting by water and other liquids.
One such application is in biomedical implants, as the surface has
good biocompatibility. There are many areas where custom designed surfaces
can improve the efficiency and function of every day commodities.
Plasma deposition of graphene is one key technology which will allow for
mass production of coated items. Shown below is our custom deposition
chamber for testing plasma chemistries and surface preparation on coupon
Graphene can also be prepared by placing ordinary graphite in a supercritical
carbon dioxide chamber, then venting the chamber rapidly, which fractures
the graphite into multi layer sheets of graphene. Shown below is the
pressure tank used in these experiments and some high quality multi layer
