Thermal Conductivity of 2D Materials
Thermal transport in 2D materials is an important consideration during the synthesis of layered materials by exothermic chemical vapor deposition and during operation of 2D electronic devices. The USC and Missouri teams have developed a computational framework to accurately describe thermal transport in transition metal dichalcogenides using molecular dynamics simulations.
The research team from the University of Missouri has developed a workflow to construct empirical non-reactive forcefields that can accurately describe the structural, mechanical and thermal properties of two dimensional and layered materials.
The USC center team led by Prof. Vashishta has expanded upon the work by incorporating quantitatively the effect of quantum mechanically accurate specific heat correction to thermal conductivity and the influence of naturally occurring isotopic distribution to provide the most realistic estimation of two dimenstional thermal conductivity.
