Abstract

We propose adjustment of the confined energy levels, En, in a quantum well structure to optimize we1 1 operation. The allowed energy levels for an electron in a potential well is related to the effective mass of an electron Mk, and the width, L, of the well. The number of allowed energy levels that can fit in a potential well is related to MZ, L and Vc. Figure 1 shows the bandgap profile for a single quantum illustrating two energy levels El and E2 in the well. As long as En < Vc, the energy level will be confined to the well. The energy levels in the well may be defined by Equation 1:
