Masselink, W. Ted, Ph. D. Prof. (Experimental Physics / Elementary Stimulation and Transport in Solids)
Duration of project: 06/2019 - 05/2022
Financer: DFG: SachbeihilfeThere are two scattering mechanisms in quantum cascade lasers (QCLs) that give rise to a parasitic (non-radiative) current in the transition region, thus limiting the efficiency: inelastic longitudinal-optical (LO)-phonon assisted scattering and elas ...
