# Magnetosubband and edge state structure in cleaved-edge overgrown quantum wires in the integer quant

@article{Ihnatsenka2006MagnetosubbandAE, title={Magnetosubband and edge state structure in cleaved-edge overgrown quantum wires in the integer quant}, author={S. Ihnatsenka and Igor V. Zozoulenko}, journal={Physical Review B}, year={2006} }

We provide a systematic quantitative description of the structure of edge states and magnetosubband evolution in hard-wall quantum wires in the integer quantum Hall regime. Our calculations are based on the self-consistent Green's function technique where the electron and spin interactions are included within the density functional theory in the local spin density approximation. We analyze the evolution of the magnetosubband structure as magnetic field varies and show that it exhibits different…
