Abstract
Photoabsorption and photoresponse of Si/Si1-xGex quantum wells are stu died by using 45 degrees unpolarized light field. Besides the free car rier absorption, the absorption peaks corresponding to both intersubba nd and intervalence band transitions are observed. We find that the in tervalence band transitions are Ge composition dependent, but the inte rsubband transitions are not sensitive to Ge composition.
