Dr. Steven Paul Hepplestone areas of research is in theoretical physics, with a principle focus on interfaces and their application to renewables.
Interfaces
The physics behind joining two materials together and their resultant properties is highly fascinating. New materials can form, which are supported by the effects created by the two adjacent "bulk" materials. On its own, the search for and discovery of new materials is exciting, but add to this the additional factors arising from interfaces and there is a multitude of interesting things to explore.
Renewables
Our planet is in crisis, and as scientists, we are in a race against time to find technologies that may help us mitigate or avoid a climate disaster. This can be rechargeable batteries, thermoelectrics, solar cells or new ways to produce clean fuels but all of these have critical role to play in our future society. As a theorist, developing new materials and technologies to tackle this is one aspect of our research. In addition, theory can help tackle how to optimise a material or device and often provide critical data to industry and experimentalists as to how to get a device optimised or working.
