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。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
