General model for the computation of energy Eigen values in aperiodic multiple quantum well structures

A general model for computation of energy states in aperiodic multiple quantum well (MQW) structures has been proposed. The MQWs are aperiodic and asymmetric with varying well and barrier widths. The tunnelling probability of the electrons through these aperiodic barriers has been studied by assuming coupling between adjacent pairs of wells. Effect of the barrier dimensions on tunnelling properties has also been investigated. The computation is based on the transfer matrix method.
