Spatially Resolved Transport

During the course of my PhD, I have developed an open-source software package called SpaRTaNS to perform spatially-resolved transport by solving the steady-state Boltzmann transport equation in three real-space and three momentum-space dimensions.

SpaRTaNS is “carrier-agnostic”, and so far we have used it to investigate thermal interface resistance of semi-coherent interfaces and the importance of microscopic interactions in electron hydrodynamic flows.
