势垒中粒子波包的运动

Wave Packet Dynamics of Particles in Potential Barriers

本文用高斯波包对粒子的运动进行描述,通过数值求解含时薛定谔方程对二维电子气中波包的运动进行研究.通过对不同能量时波包透射性的研究,阐明了其粒子性和波动性.在我们的工作中,波包宽度不同,透射率与能量的关系不同.

We use Gauss wave packet to describe the dynamics of charged particle in a limited two-dimensional electron gas by sloving time-dependent SchrOdinger equation. The particle character and wave character of wave packet with different energy are illustrated by the transmission of wave packet. In the present work, for different wave packet width the transmission shows different relationship with the input energy.
