Abstract

Multiple Finite Quantum Well structure under transverse magnetic field action has been analyzed theoretically by means of the behavior of the carriers wavefunctions. Confluent hypergeometric functions as analytical solutions of the carriers effective-mass equation appear to us to be a powerful tool for the study of several physical properties of superlattices. In particular, the electrons and holes magnetotunneling times through the barrier separating two close wells have been calculated. It is found that the escaping time can be lower than the radiative recombination time, depending on the barrier widths and magnetic field intensity and, therefore, allowing the tunneling of the carriers.
