Our research is focusing on understanding thermal transport properties using experimental techniques. By doing so, we aim to develop better materials for various applications, such as thermal management of electronic devices or thermal insulation.

heat transfer in-situ and in-operando

As an optical technique, our TDTR setup can be used to study heat transfer in-situ and in-operando with improved accuracy and robustness. With such ability, we aim to study heat transfer with pressure, intercalation, etc. (in-situ) and under different working conditions of electronic devices (in-operando).

phonon transport

The dominant heat carrier in semiconductors is phonon. Phonon transport determines thermal transport properties in a material. We study phonon transport processes, with particular interest in phonon scattering by complex lattice imperfections (such as dislocations) and phonon transport across interfaces.

develop new thermal measurement techniques

Electronics are getting small, and that is preventing not only heat dissipation due to high power density, but also measurement of thermal properties at the nanoscale and atomic level. Our goal is to develop new tools to measure thermal properties at samller scales by employing advanced optical techniques.
