摘　　要：构建了不对称的M形势垒,用薛定谔方程和airy函数推导出电子的透射系数.基于势垒的3种不对称模型,讨论了电子的透射系数和共振隧穿情况,系统地比较了不对称和对称M形势垒的共振隧穿,得出不对称性对共振隧穿的影响.By constructing an asymmetric M-shaped potential barrier model,we derived the electron transmission coefficient by using the Schr dinger equation and Airy function.Based on three asymmetric models of potential barriers,we discussed the transmission coefficient and resonant tunneling of electrons,and systematically compared the resonant tunneling of asymmetric and symmetric M-shaped potential barriers,and declared the influence of asymmetry on resonant tunneling.

关 键 词：M形势垒 透射系数 共振隧穿
