Calculation of optical gain in AlGaN quantum wells for ultraviolet emission

Autor: Bernd Witzigmann, Friedhard Römer, Martin Martens, Christian Kuhn, Tim Wernicke, Michael Kneissl

Publikováno v: AIP Advances, Vol 10, Iss 9, Pp 095307-095307-5 (2020)

Stimulated emission from AlGaN based quantum wells (QWs) emitting at ultraviolet wavelengths is investigated theoretically. Maxwell–Bloch equations in the second Born approximation are solved self-consistently with the Poisson equation. The valence

Multiband k · p model and fitting scheme for ab initio-based electronic structure parameters for wurtzite GaAs

Autor: Marquardt, Oliver, Caro, Miguel A., Koprucki, Thomas, Mathé, Peter, Willatzen, Morten

We develop a 16-band k · p model for the description of wurtzite GaAs, together with a novel scheme to determine electronic structure parameters for multiband k · p models. Our approach uses low-discrepancy sequences to fit k · p band structures b
