Wong, and EFRC scientists François Léonard, Qiming Li, and George T. Wang, present a theoretical  and computational study of the electronic properties of core/shell nanowires.  They [...]

July 4, 2011 [singlepic id=980 w=320 h=240 float=right]Solid-state lighting is currently based on light-emitting diodes (LEDs) and phosphors.  Solid-state lighting based on lasers would offer significant advantages including high potential efficiencies at high current densities. Light emitted from lasers, however, has a much narrower spectral linewidth than light emitted from LEDs or phosphors.  Therefore it [...]
