Energy states of finite-barrier quantum wires in the presence of an external electric field

Abstract

Energy level shift in finite-barrier quantum wires systems is found to be enhanced in comparison to finite-barrier single quantum well systems. The ground-state solutions of the two-dimensional Schrödinger equation are obtained using the inverse power method combined with the successive over relaxation method. In addition, the two-dimensional changes in the wave function due to an external electric field in cylindrical quantum wires are presented.
