摘要：
We use the eight-band k.p model to describe the infrared inter-subband absorption in Si-Si1-xGex-Si quantum wells, which takes explicitly into account the Gamma'(25)(Gamma(8)(+) + Gamma(7)(+) in the double group) valence band and the second conduction band Gamma(2)'(Gamma(7)(-)). We then obtain an accurate description of mixing of the S wave function with the valence band functions.
