摘要

纳米结构中非平衡热输运的准确建模需要对声子色散关系的适当描述和对各种非调和效应的适当处理。在这项工作中,我们开发并使用了一个耦合的VFF分子力学-蒙特卡罗(VFF- mc)平台来求解声子玻尔兹曼输运方程(BTE),用于模拟具有特定几何形状的纳米结构中的导热性。

VFF-Monte Carlo framework for phonon transport in nanostructures
Accurate modeling of non-equilibrium heat transport in nanostructures demands an appropriate description of phonon dispersion relation and proper treatment of various anharmonic effects. In this work, we develop and employ a coupled VFF molecular mechanics-Monte Carlo (VFF-MC) platform to solve the phonon Boltzmann Transport Equation (BTE) for modeling thermal conductivity in nanostructures having specified geometry.
