Biography
The goal: Grow novel semiconductor materials, characterize their optical and eletrical properties, and fabricate novel optoelectronic devices. Sucessful intergration of these tasks will create enabling photonic technologies. This lab works with wide band gap semiconductors includling Gallium Nitride and Zinc Oxide and a variety materials to make quantum dots and other nanostructures.
