✦ Synopsis

Many people have studied the conductance properties through an array of anti-dots, especially since the observation of Weiss oscillations. In most cases, however, in which the recursive GreenΕΊs functions are used on a spatial lattice, periodic boundary conditions are employed. In this paper, we analyse the effects of boundary conditions and magnetic field on the conductance behavior in a number of anti-dot-shaped, GaAs/AlGaAs 2DEG quantum systems. The effect of periodic boundary conditions causes a reduction in the overall conductance. The effect of changing the boundary conditions is more profound for lower numbers of anti-dots.

An analytical approach to the problem of the Wannier-Mott exciton in a semiconductor quantum well (QW) in the presence of external magnetic and electric fields is developed. The magnetic field is taken to lie in the heteroplanes while the electric field is directed perpendicular to the heteroplanes.

An analytical approach to the problem of a negatively charged donor in a quantum well in the presence of a strong magnetic field directed perpendicular to the heteroplanes is developed. The double-adiabatic approximation is used. Firstly, the transverse motion of the electron caused by the strong ma
