Zeeman effect in wurtzite-based and strained cubic heterostructures

We investigate theoretically the Zeeman effect on the lowest confined subba nds 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 A(II)B(VI) h eterostructures, in the framework of the quasi-cubical Kane model. In our c alculation we make allowance for the strain in heterolayers and huge intern al electric fields due to spontaneous polarization and lattice-constant mis match between the compositional materials.
