Abstract:

The sp3 tight-binding method has been applied to calculate the in-plane anisontropy of optical matrix elements for indirect electron-hole radiative recombination at a type-II interface. It has been shown that in type-II heterostructures with large band off-sets the linear polarization of the photoluminescence vary in a wide range including values 100 as a function of the tight-binding parameters characterizing the interface cations and anions. The behaviour of electron and hole quantum-confined states near the interface and their overlap has been analyzed as well.
