Witryna1 sie 2024 · The binding energy of a donor impurity in a wurtzite GaN/Al x Ga 1-x N core-shell nanowire is investigated by a variational method combined with a finite-difference algorithm. A semi-empirical formula is derived to express the temperature dependence of static dielectric constants for wurtzite structure. The temperature … Witryna1 sty 2024 · Low temperature grown p-AlGaN layer with a small resistivity is crucial to improve the performance of the GaN-based laser diodes (LDs). In this study, growth temperature of the p-Al x Ga 1-x N (0.08 ≤ x ≤ 0.104) layers are controlled to be relatively low, and the influence of hydrogen impurity on the resistivity is investigated in …
