Keywords:
Quantum well, high-κ dielectric, screening, impurity scatteringAbstract
The effect of screened ionized background impurities on electron scattering in HfO2/InSb/HfO2 two-dimensional (2D) nanostructure is considered. The expression of differential scattering cross-section depending on the 2D screened Coulomb potential analytical features is calculated analytically. A numerical analysis of the scattering relaxation time in the presence of electronic screening and quantum well/high-κ dielectric heterojunction effects is carried out. Taking these effects into account, a substantial suppression of electron scattering is obtained.
