Our research goals focus on:
(i) fabrication of advanced materials to enhance energy conversion efficiency in solid-state devices;
(ii) developing novel thermal devices at the micro- and nano-scale for thermal management applications;
(iii) developing better metrology techniques for accurate and high spatial resolution characterization of thermal and thermoelectric properties of materials and interfaces;
(iv) integrating these materials into systems that generate residual heat to harvest or reuse that energy.
Our work includes nano- and micro-fabrication, characterization and multiscale simulations. On-campus collaborations include Material Science, Physics, Chemical, Mechanical, Fluid and Thermal Engineering.
