Dr. Harris utilizes molecular beam epitaxy (MBE) of III-V compound semiconductor materials to investigate new materials for electronic and optoelectronic devices. He utilizes heterojunctions, superlattices, quantum wells, and three-dimensional self-assembled quantum dots to create metastable engineered materials with novel or improved properties for electronic and optoelectronic devices. He has recently focused on integration of photonic devices and micro optics for creation of new minimally invasive bio and medical systems for micro-array and neural imaging.
His current research interests are in the physics and application of ultra-small structures and novel materials to new optoelectronic and spin based devices. He has supervised over 95 PhD students and has over 850 publications in these areas.
