SCREENED IMPURITY ENERGY OF QUANTUM WELL WITH THE HIGH-k TYPE DIELECTRIC CONTRAST

Abstract

Quantum well / high-κ type barrier dielectric mismatch related problem is elaborated from the first principles. An influence of the Debye-Hückel type potential analytical features on the screened impurity binding energy is considered for the first time. Inclusive numerical analysis of both high-κ barrier/quantum well/high-κ barrier and low-κ barrier/quantum well/high-κ barrier two-dimensional structures on the basis of InSb/HfO₂ heterointerface is investigated.
