Time to restart efficiency droop debate again?

Xiaohang Li - July 25, 2016

Prof Van de Walle's group published an APL paper in 2009 stating that the Auger coefficient of blue and green InGaN (~2.5eV) is very large (~1e-30 cm6s-1). This becomes one of the strongest evidences about why Auger recombination is THE dominant reason for efficiency droop​.
