Simulator for Phonon Transport in Arbitrary Nano-Structure (P-TRANS) is a Monte Carlo ray tracing software to model phonon transport in arbitrary nanostructure. The software is developed by Shiomi’s Lab at The University of Tokyo and is sponsored by TherMAT project.

Here is an illustration on how the software works:


Just waiting for a few seconds in front of a normal desktop, you can get a variety of thermal conduction properties of nanostructured materials, which is crucial for high-performance thermoelectric materials design.
