The introduction of a small amount of impurities or point defects in a crystalline semiconductor may change the electric properties over several orders of magnitude, … Witryna10 lut 2024 · ABSTRACT. The effect of In-doping on the quantum information entropy of the hydrogenic impurity states in the In x Ga 1-x N quantum dot has been studied for the first time. By exploring the Shannon entropy in the position space (S r), in the momentum-space (S p) and the Shannon entropy sum S t, we find some novel and … WitrynaThe spatial localization is the most basic feature of an impurity state(IS) in a semiconductor.
