Electronic and optical properties of (001) Si/ZnS heterostructures

Abstract
A theoretical characterization of (001)-grown (Si2)m/(ZnS)2m multiple quantum wells is presented. Confined states in the Γ1c well have strong X1c and light-hole admixtures, and there are two types of hole states in the valence band. Strong intersubband transitions can be exploited in the infrared for both n - and p -doped devices.
