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.
A simple Kronig-Penney model for 1D mesoscopic systems with disordered f-peak and finite width potentials is used to study numerically the influence of a constant electric field on the conductance fluctuations and probability distribution. The electric field applied to such systems allows us to obta
