Ge/SiGe quantum wells," 4th International Conference on Group
IV Photonics, Tokyo, Japan, September 2007, Paper ThA4
We resolve photoinduced changes in carrier populations of Ge/SiGe quantum
wells using femtosecond pump-probe spectroscopy.
Absorption transients < 400fs indicate rapid Г→L
intervalley scattering that may explain exciton linewidth and suggest
saturable absorber applications.
