Gao Min is a Professor of Energy Materials and Head of Thermoelectric Laboratory. He obtained BSc in Semiconductor Physics from Xidian University, China and PhD under supervision of Professor D M Rowe in Thermoelectrics at Cardiff University UK. His main research interests focus on fundamental understanding of thermoelectric processes for energy harvesting applications.

He is a Board Member of European Thermoelectric Society and also serves as an expert evaluator for H2020, DOE (USA), NSF (USA), NWO (NL), DFF (DK), NSF (CN) and EPSRC (UK) on energy materials, promoting truly excellent research in thermoelectrics and related energy materials.

He has over 25-year experience in thermoelectric research. In early 1990s, he initiated the research in the use of the Peltier modules as generators for waste heat recovery and subsequently developed an improved TE module theory to demonstrate the potential economic benefits even using low efficiency TE modules. This work has contribution to the recent resurgence of interest in thermoelectrics.

In 1994, his work on improving the power factor by employing multiple potential barriers contributed to the development of energy filtering concept. He was the first to propose the fabrication of TE micro-coolers using IC and MEMS technologies and demonstrated theoretically the feasibility. In 2000, his empirical analysis of known thermoelectric materials identified a ZT barrier, putting a realistic upper-bound on the PGCE approach.

Recently, his work focuses on developing novel characterisation techniques that enable investigation of the thermoelectric processes on wide and deep scale, such as high-throughput thermoelectric measurement system based on novel multifunctional probe; thermoelectric impedance spectroscopy; dual I-V curves for complete characterisation of thermoelectric devices.

A new emerging area of his research is to explore innovative and economically viable concepts for full-spectrum solar energy harvesting based on hybrid PV-TE systems. The current research focuses on development of new type of solar cells, concentrators and systems that facilitates the integration with thermoelectrics.

New concepts proposed by him with his co-workers included: improving thermoelectric efficiency using Fermi-gas/Fermi-liquid interfaces; thermoelectric property-structure diagram; ring-structured thermoelectric module; regenerative thermoelectric combustion system; improving cooling performance by thermo-electro-photon process; variable thermal resistor; improving the thermoelectric efficiency through pulse mode operation; preparation of thermoelectric nanoparticles using ultrasonic milling; new generation low cost thermoelectric materials based on AlFeTi; and heavy fermion/superconductor tunnelling junctions for millie-Kelvin refrigeration.
