Localization Effect in Photoelectron Transport Induced by Alloy Disorder in Nitride Semiconductor Compounds

Mylene Sauty et al.

Summary: Near-band-gap photoemission spectroscopy experiments were conducted on p-GaN and p-InGaN/GaN photocathodes activated to negative electron affinity. The results showed that the photoemission quantum yield of InGaN samples with higher indium content dropped by more than an order of magnitude when the temperature decreased, while it remained constant for samples with lower indium content. This drop was attributed to the freezing of photoelectron transport in p-InGaN due to electron localization induced by alloy disorder.

Quantitative correlation of hot electron emission to Auger recombination in the active region of c-plane blue III-N LEDs

Wan Ying Ho et al.

Summary: Using electron emission spectroscopy, energy distribution of vacuum emitted electrons from a commercial blue LED was studied, revealing improved signal-to-noise ratio on thin p-GaN LED and proportional relationship between hot electron integrated peak intensity and carrier density. Auger recombination was identified as the dominant cause of efficiency droop.
