中文摘要	in this paper, we propose an n-type vertical transition bound-to-continuum ge/sige quantum cascade structure utilizing electronic quantum wells in the l and gamma valleys of the ge layers. the optical transition levels are located in the quantum wells in the l valley. the gamma-l intervalley scattering is used to depopulate the lower level and inject the electrons into the upper level. we also show that high quality si1-ygey pseudosubstrate is obtained by thermal annealing of si1-xgex/ge/si structure.
