Abstract

In this work, an efficient method is proposed to calculate the miniband structure and density of states for well-ordered Ge/Si-nanodisk array. Within the envelop-function framework, our approach surmounts theoretical approximations of the multi-dimensional Kronig-Penney method and provides a guideline for three-dimensional quantum dots design by simulating the effect of the interdot space on miniband structure.
