Abstract: Numerical simulation is carried out to determine of first three eigenstates of a multiple quantum well structure for both constant and variable effective mass cases where BenDaniel-Duke boundary condition is introduced for computation of effective mass mismatch along with the consideration of potential barrier dependence on material composition of higher band-gap material. Dimensional asymmetry is introduced to observe the change in eigenvalue, and no. of layers is also varied to observe the same in absence of electric field. GaAs/AlxGa1-xAs material composition is considered for simulation purpose to estimate tunneling probability. Variation of mole fraction provides a shift in eigenenergies for resonance transmission.
