NM02 – Impact of random alloy fluctuations on the electronic and optical properties of c-plane AlxGa1−xN/AlN quantum wells

Finn R., Schulz S.

We present a theoretical study of the electronic and optical properties of c-plane AlxGa1−xN/AlN quantum wells emitting in the ultraviolet-A (UV-A) to UV-C spectral range. Special attention is paid to the impact of alloy fluctuations on the results. We find that random alloy fluctuations in (Al,Ga)N are already sufficient to cause strong carrier localization effects.
