Thermoelectric materials generate a voltage from a temperature gradient. Thermoelectric generators made from these materials can recover waste heat and convert it into electrical power. These devices have potential for powering small electronic devices, and in the future a thermoelectric generator placed on someone’s skin could even generate electricity from their body heat to power a wireless medical sensor. However, significant materials challenges still need to be overcome in order to obtain high thermoelectric figure of merit (ZT) materials and efficient devices.
One promising new class of thermoelectric materials are the halide perovskites. These materials have been studied extensively for photovoltaics, and it is known that they have low thermal conductivity and high charge mobility – both of which are important for thermoelectrics.
This project will focus on development of halide perovskite materials for thermoelectric applications. There will be a particular emphasis on (i) controlled electrical doping, and (ii) structural optimisation by bottom-up nanostructuring.
The project would suit someone with a physical science background (physics, materials science, physical chemistry), motivated by the process of understanding and developing semiconductor materials. Direct experience in the topic of the project is not a requirement, but the candidate may benefit from experience in any of the following areas:
• Materials characterisation.
• Thin film deposition.
• Electrical testing.
• Semiconductor devices.
• Halide perovskite materials.
• Thermoelectric materials.
