Band alignment of III-N, ZnO and II-IV-N2 semiconductors from the electron affinity rule

Band alignment of III-N, ZnO and II-IV-N2 semiconductors from the electron affinity rule

The natural band alignment between various II-IV-N2 and III-N and ZnO semiconductors are determined by means of first-principles surface calculations of their electron affinities. While these ignore specific interface dipole formation and strain effects, they provide a first guidance to the construc...

Zusammenfassung:The natural band alignment between various II-IV-N2 and III-N and ZnO semiconductors are determined by means of first-principles surface calculations of their electron affinities. While these ignore specific interface dipole formation and strain effects, they provide a first guidance to the construction of heterojunction devices involving this family of materials.
