| Popis: | Optoelectronic devices based on intersubband transitions (ISBT) typically require surface texturing after growth, to overcome the selection rules for polarization and operate under normally incident light. The authors demonstrate that $m$-plane ZnO/(Mg,Zn)O multiple quantum wells (QWs) self-assemble in a geometry that allows absorption at normal incidence, depending on the polarization state of the light with respect to the $c$ axis. These multiple QWs behave as a self-assembled metamaterial, a building block for polarization-sensitive optoelectronic devices. |
