摘要

在这项工作中，我们从求解Schrödinger方程得到的波函数中计算Wigner函数。我们的目标是通过解决维格纳输运方程来研究我们在模拟设备时遇到的问题，即边界和邻近区域之间的数值差异。本文主要讨论了单势垒和双势垒器件中势垒高度对边界条件的影响。

Study of the Wigner function boundary conditions at different barrier heights

In this work, we compute the Wigner function from wavefunctions obtained by solving the Schrödinger Equation. Our goal is to investigate issues that we encounter when simulating devices by solving the Wigner transport equation, namely the numerical discrepancies between the boundaries and the neighboring regions. In this paper, we focus on how the boundary conditions are affected by the barrier height in single- and double-barrier devices.
