Nano Electronic and Thermal Transport
The focus of the group is to understand the mesoscopic transport properties of low-dimensional quantum materials and heterostructure systems in the nanoscopic regime. By understanding the intrinsic properties of electrons and the dynamics of phonons and photons, we can effectively manipulate the electrical, thermal, thermoelectric and excitonic transport of these quantum systems at the atomic scale. This in turn can be transformed and developed into scalable novel technological applications in high-performance electronics, energy harvesting, sensing, and computing devices.
