Abstract
AbstractResults for our fully frequency‐ and wavevector‐dependend self‐consistent nonequilibrium Green's function simulations of electron transport through quantum cascade lasers are compared to those from a simplified approach where scattering rates are only evaluated at representative ‘typical values’ of the in‐plane momentum due to the complexity of the underlying many‐body problem and the limited computational resources available. We find a noticeable impact on electronic lineshapes. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
