Research Activities  

Our research activities are focused on the analysis of chemistry, microstructure, and electrical properties of electronically-functional interfaces. We are interested in a range of materials including but not limited to wide bandgap semiconductors; carbon-based semiconductors and nanostructures; organic semiconductors; metal-semiconductor interfaces; dielectric-semiconductor interfaces, as for example in metal-oxide-semiconductor (MOS) devices; and thin films. We are also interested in a range of applications, especially renewable energy technologies and chemical sensing, and associated electronic devices, such as solar cells and field-effect transistors (FETs). Examples of current research projects include the development of conductive contacts to nanostructured carbon an diamond thin films; understanding the effect of defects on Schottky and ohmic contacts to silicon carbide (SiC); the development of thermally-stable interfaces for solid-state semiconductor gas sensors based on SiC and aluminum gallium nitride (AlxGa1-xN); investigation of ohmic contacts to polythiophenes for organic devices, such as organic light emitting diodes (OLEDs) and organic photovoltaics (OPVs); inket printing of conductive contacts on semiconductors for macroelectronics.
