Investigation of magnetic materials and devices include characterization of nanoscale electronic properties by proximal probe charging of Co nanoclusters and the application of magnetic materials in semiconductor devices for magnetic field sensing

I am currently a postdoctoral researcher in Prof. Edward T. Yu's Nanoscale Characterization and Devices Laboratory at the University of California, San Diego, San Diego, USA.  I graduated in July 1997 with a Diploma degree in physics from the research group of Prof. Birringer at the Saarland University, Saarbrücken, Germany. In February 1999, I obtained a Masters Degree in Electrical Engineering (Applied Physics) from UCSD, and in June 2003 I finished my graduate studies with a Ph.D. Degree in Electrical Engineering (Applied Physics).  My research focuses on the nanoscale electronic properties of semiconductor and magnetic materials and devices.  Investigation of magnetic materials and devices include characterization of nanoscale electronic properties by proximal probe charging of Co nanoclusters and the application of magnetic materials in semiconductor devices for magnetic field sensing. Work on the electronic properties of semiconductor materials and devices is primarily concerned with AlGaN/GaN heterostructure field-effect transistors. Scanning capacitance microscopy and local capacitance spectroscopy are used to study lateral threshold voltage variations and the frequency response of trap states.
