摘要：
The temperature dependence of the electron mobility in ZnMgO/ZnO heterostructures in the Bloch-Gruneisen regime is studied and many-body effects are taken into account. For sufficiently low temperatures, the mobility limited by acoustic scattering follows a stronger, mu similar to T-alpha (alpha = 8.5 for the deformation-potential scattering, alpha = 6.5 for the piezoelectric scattering), temperature dependence, which is significantly different from the traditional mu similar to T-1 law. Many-body effects play an important role in the electron transport. The theoretical calculations are able to explain recently published experimental data.
