Peter Griffin

Peter Griffin is a PhD student contributor to Physics World. Peter is a student in the Cambridge Centre for Gallium Nitride. His work looks at nanostructuring nitride semiconductors by an electrochemical process where he creates sponge-like porous structures. This porosity can be used to improve or alter parts of an LED to change the light it produces or make it more efficient. It also has applications in sensors, as there is a very large surface area of the porous regions. As well as his research he enjoys teaching, which he sees as a lovely bonus of academia. He also spends lots of time backstage in theatres building sets and doing lighting.
