摘要：

Electron mobility in Cd0.8Zn0.2Te is calculated by an iterative solution of the Boltzmann equation and compared with recent measurements over the temperature range 160-320K. Polar optic, alloy disorder, and acoustic scatterings via deformation potential and piezoelectric interactions are included in the calculations. The mobility is found to be predominantly controlled by polar optic phonons. Piezoelectric scattering contributes the least, and deformation potential acoustic scattering is weaker than alloy disorder scattering. The alloy scattering potential to fit the experiments is found to be almost half that predicted by the band-gap difference of the electron affinity difference between CdTe and ZnTe.
