Overview:
Our mission is to explore the physical effects of energy transport particularly in nanoscale structures to obtain a better understanding of the physical world that can lead to engineering discoveries in energy applications. Specifically, we focus on modeling nanoscale energy transport (phonons, electrons, and photons) in semiconductor devices designed for energy applications. This includes thermoelectric devices, solar cells, and batteries, for example. We also study fundamental artifacts of small-scale transport such as thermal rectification, interfacial conductance in nanostructured materials.Selected Publications:
