摘要
利用传递矩阵方法精确计算了一维定态薛定谔方程,求解出电子穿过矩形势垒的透射系数,进一步研究了该透射系数与有效质量和矩形势垒参数的关系。数值计算结果表明,有效质量和矩形势垒参数对透射系数的影响同等重要。
Transmission coefficient of electron tunneling through rectangular barrier has been calculated based on the exact solution of the one-dimensional time-independent Schrodinger equation with the transfer matrix method ; furthermore , the dependence of the transmission coefficient on the effective masses and parameters of rectangular barrier also has been studied. Numerical analysis shows that the effective masses cannot be ignored in comparison with parameters of rectangular barrier for the transmission coefficient.
