• Developed, built, and maintained a Remote Oxygen Plasma (ROP) processing system to remove surface adsorbates and control native defect densities in oxide semiconductor materials• Designed, built, and maintained a UHV metals deposition chamber with interchangeable mask system to deposit high quality Ohmic and Schottky contacts with high precision and repeatability• Characterized the temperature and process dependent segregation of defects and dopants while identifying the carrier density dependence on acceptor type defects in degenerately doped ZnO films using a complement of electrical and optical techniques• Identified the polarity dependence and electrically-active native point defect driven growth mechanisms behind spontaneous nanostructure formation on single crystal Zn- and O-polar ZnO surfaces• Identified the threshold dependence between surface roughness and optical efficiency thereby revealing the significance of mono-layer surface roughness to minimize surface recombination by free carrier defects and emphasizing the importance of surface preparation• Responsible for the operation and maintenance of a Scanning Probe Microscope , Surface Photovoltage Spectroscopy configuration, and Remote Oxygen Plasma chamber
