Carbon Nanostructures

Short Description: 
The focus of this group is the growth and characterization of various carbon materials with an emphasis on electronic and biological properties. Doped and un doped nano and polycrystalline diamond, diamond like carbon, and carbon nanotubes are the interests of the research. The deposition of these materials is performed in two plasma CVD chambers and a hot filament system. The characterization techniques used to study their properties are AES, LEED, XPS, ARUPS, Raman Spectroscopy, Field Emission and Thermionic Field Emission Measurements, PEEM, AFM, and EFM. Electron emission properties are studied for a variety of applications including compact field emission devices and thermionic energy converters. The biological response to these materials is also examined with an emphasis on blood compatibility.
