Description

First-principles studies of recombination mechanisms in light emitters

Chris G. Van de Walle

Materials Department, University of California, Santa Barbara, USA

The efficiency of light emitters is limited by loss mechanisms that are experimentally difficult to probe.  I will discuss the theoretical advances that are enabling us to quantitatively evaluate the rate of nonradiative processes such as Auger recombination and defect-assisted carrier recombination.  Our approach allows us to suggest specific strategies for increasing the efficiency of nitride or halide perovskite light emitters, and is also applicable to quantum emitters.
