Zeeman Effect in Wurtzite-Based and Strained Cubic Heterostructures

Abstract

We investigate theoretically the Zeeman effect on the lowest confined subbands in wurtzite heterostructures. The powerful approach suggested recently for zincblende-based nanostructures is extended to a new symmetry class and analytical expressions are derived for the first time for the g-factors in the technologically important nitride-based quantum wells and AIIBVI heterostructures, in the framework of the quasi-cubical Kane model. In our calculation we make allowance for the strain in heterolayers and huge internal electric fields due to spontaneous polarization and lattice-constant mismatch between the compositional materials.
