Sirringhaus Lab

 

Biography

Under the supervision of Professor Henning Sirringhaus in Cavendish Laboratory, Cong Zhao currently focuses on investigating charge carrier’s dynamics in all kinds of organic semiconductors as well as perovskite materials, specifically in terms of their thermoelectric applications. Via tools such as transistor structure, Kelvin Probe Force Microscopy (KPFM), Electron Spin Resonance (ESR), Atomic Force Microscopy (AFM), Fourier Transform Infrared and so on, he characterizes charge mobilities and electronic conductivities, thermal conductivities, power factors and Seebeck Coefficient of OTE materials and investigate the underlying property-structure relationships in OTE systems, which, promisingly, will pave the way for chemical design of outstanding materials with large-mobility, low-thermocondutivity and highly efficient thermal-electric conversion.
