Abstract

By using Monte Carlo simulations of the Wigner–Boltzmann transport equation, the validity of a smooth quantum hydrodynamic model has been investigated in a GaAs Resonant Tunneling Diode. The common approximation of the heat flux by Fourier’s law is shown to differ substantially from the actual heat flux.

关于共振隧道二极管中傅立叶定律的有效性

通过使用 Wigner-Boltzmann 传输方程的蒙特卡罗模拟，研究了 GaAs 共振隧道二极管中平滑量子流体力学模型的有效性。结果表明，用傅里叶定律对热通量进行的普通近似与实际热通量存在很大差异。
