Article Synopsis
- Non-radiative Auger-Meitner recombination processes in III-nitride optoelectronic devices can lead to efficiency drops at high temperatures and carrier densities, but understanding of these processes in UV-operating devices is limited.
- The study investigates the temperature dependence of Auger-Meitner recombination in (Al,Ga)N/AlN quantum wells using a model that considers alloy fluctuations and carrier localization effects.
- Results indicate that while radiative recombination slightly increases with temperature, Auger-Meitner recombination may decrease, suggesting that other non-radiative processes outside the active region are likely responsible for the thermal efficiency drop in these devices.
