TRANSMISSION CHARACTERISTICS INCLUDING THE COUPLING EFFECT BETWEEN NORMAL AND LATERAL DEGREES OF FREEDOM IN SINGLE BARRIER STRUCTURES WITH A LONGITUDINAL MAGNETIC-FIELD

Within the parabolic conduction-band approach, a modified one-dimensio nal effective mass Schrodinger equation, including the magneto-couplin g effect between the longitudinal motion component and the transverse Landau orbits of an electron, is strictly derived, This magneto-coupli ng effect is generated from the space-dependent effective mass of the electron, Numerical calculations for single barrier structures show th at the magneto-coupling has a series of important effects on the trans mission probability and the above-barrier quasi-bound stales. We sugge st that the magneto-coupling effect may be observed by measurements of the optical absorption spectrum in the single barrier structures. (C) 1997 Published by Elsevier Science B.V.
