Concept illustration of non-radiative recombination, in which electron-hole interaction at a defect in the atomic structure results in heat, rather than light, being emitted. Jim Speck will use his Vannevar Bush Award to advance understanding of the physics of such interactions. Illustration by Fangzhou Zhao, Van de Walle group.
Jim Speck Wins Vannevar Bush Award
The $3-million award will enable investigation of little-understood physics in gallium-nitride devices.
