| Abstract: | By numerically solving the steady - state Wigner distribution function and Poisson equation self - consistently, we calculated the bias tunnel current of the one dimension multi - barrier structure, and investigated the effect of the variable quantum well width on its current characteristics. The numerical simulation results show the quantum limit of the quantum well width, beyond which will observe the resonant tunneling phenomena. |
