Abstract

The spin-polarized density functional theory was used to calculate the spin dependent features of quantum point contacts. 3D Poisson-1D Schrödinger solver was used to obtain the self consistent Hartree potential and the sheet densities of the two-dimensional electron gas (2DEG) in the GaAs quantum well. The Schrödinger equation was solved in slices along the growth direction. It was assumed that the 2DEG is located at the average distance within the quantum well which means that the 2D Hartree potential is an accurate representation of the full 3D system.
