摘要
Inter valley scattering has a great impact on carrier mobility of strained Si materials, so based on Fermi's golden rule and the theory of Boltzmann collision term approximation, inter valley phonon scattering mechanism of electrons in nano scale strained Si (101) materials is established under the influence of both energy and stress. It shows that inter valley phonon f(2), f(3), g3 scattering rates decrease markedly in nano scale strained Si (101) materials with increasing stress. The quantized models can provide valuable references to the understanding of strained Si materials and the research on electron carrier mobility.
