Abstract
The thermal transport property is crucial for electronic devices’ performance and reliability, since it determines the efficiency of heat dissipation. Parameter-free calculations have played an increasingly important role in understanding 2D materials’ thermal transport properties. In this talk, I will explain how we calculate the thermal transport property by using Boltzmann's transport equation without any adjustable parameters, particularly from our open source ShengBTE software package (http://www.shengbte.org/). I will then illustrate this with specific 2D examples including graphene, transition-metal dichalcogenides and borophene. Finally, I will demonstrate the limit of the current treatment of the phonon boundary scattering from atomistic simulation in nanostructures.
