Material Classification of Recyclable Containers Using 60 GHz Radar
Tommy Albing, Rikard Nelander
Rather than sending used containers and materials to the landfill, recycling can help lower the human impact on the environment. However, manually sorting the mixture of incoming m…
Temperature Dependence and Screening Models in Quantum Cascade Structure
Rikard Nelander, Andreas Wacker
Different screening models in quantum cascade lasers are compared by calculating the contribution of intra-subband impurity scattering to the optical linewidth as a function of tem…
Temperature dependence of the gain profile for THz quantum cascade lasers
Rikard Nelander, Andreas Wacker
We study the rapid decrease of peak gain in resonant-phonon THz Quantum Cascade Lasers with increasing temperature. The effect of various microscopic scattering processes on the ga…
Fingerprints of spatial charge transfer in Quantum Cascade Lasers
R. Nelander, A. Wacker, M. F. Pereira +7
We show that mid infrared transmission spectroscopy of a quantum cascade laser provides clear cut information on changes in charge location at different bias. Theoretical simulatio…
