This tool allows users to calculate the phonon model temperature and heat flux in nanomaterials, including nano thin films, nanoribbons, nanowires and across interfaces. The prebuilt structures include the Si, Si/Ge interface, graphene, and graphene/BN interface. Users can uploaded any structures to do calculations. We expect this tool to pave the way towards an efficient investigation of phonon and thermal transport with applications in thermal transport. Please upload the eigenvectors obtained elsewhere (e.g. GULP) by yourself. The MD simulation may take a long time, depending on the domain size and MD steps you assign.
