Research Interests
Physical properties and device applications of metal oxide semiconductors (in particular the semiconducting oxides of zinc, magnesium, tin, indium, gallium, and their alloys). Transparent thin film transistors for high speed pixel switching in optical displays. UVB photodetectors for monitoring personal UV exposures for the prevention of skin cancer and vitamin D deficiency.
