Biography

Richard researches the growth of extreme III-nitride alloy thin films grown via plasma assisted molecular beam epitaxy (MBE). Projects include the growth of BGaN films using a novel BBr3   gas source as well as the optical and structural characterization of a broad range of InAlN thin film compositions to help understand the physics of extreme alloys. Richard grows on the Nitride Gen II MBE system.
