Nonradiative relaxation times in diagonal transition Si/SiGe quantum cascade structures

Autor: K. Brunner, Gerhard Abstreiter, Werner Wegscheider, S. Hackenbuchner, Stefan Schmult, I. Bormann

Publikováno v: Applied Physics Letters. 83:5371-5373

Here, we explore experimentally and theoretically the possibility to prolong the upper hole state nonradiative lifetime of Si/SiGe quantum cascade (QC) structures by using a spatially indirect diagonal transition between two SiGe quantum well ground
