Modeling of quantum-wire superlattices

We present a general approach to numerical calculations providing the confi ned states in semiconductor heterostructures. This method is applied to GaA s/Ga0.80Al0.20As quantum wire superlattices with a parallelogram section el aborated by the original method of structuration, the 'Atomic Saw'. Thus, t he modeling has to deal with the wire shape, the structure periodicity, and the Luttinger Hamiltonian formulation with a spin quantization z-axis para llel to the [hhk] direction. The optical properties of such heterostructure s, investigated by photoluminescence excitation and linear polarization mea surements, match well with the theoretical analysis.
