Nonequilibrium Green’s functions theory: Transport and optical gain in THz quantum cascade lasers
24 Mar 2010 | Online Presentations | Contributor(s): Tillmann Christoph Kubis
Quantum cascade lasers (QCLs) are promising sources of coherent THz radiation. However, state of the art THz-QCLs are still limited to cryogenic temperatures. The charge transport in these QCLs is subject to coherent quantum phenomena, such as quantum tunneling, confinement and interferences as …

Quantum transport in semiconductor nanostructures
03 Mar 2010 | Publications | Contributor(s): Tillmann Christoph Kubis
PhD thesis of Tillmann Christoph Kubis
The main objective of this thesis is to theoretically predict the stationary charge and spin transport in mesoscopic semiconductor quantum devices in the presence of phonons and device imperfections. It is well known that the nonequilibrium Green's function …
