Research interests

In short, our research investigates nano materials for making better energy devices. 

The aim is to enhance the electronic, optical and thermal properties of silicon-based materials through changes at the nano-scale – usually involving nano-structuring or the introduction of nano-scale defects.

This makes these semiconductors better for applications in energy harvesting devices, such as photovoltaic cells or thermoelectric generators.

While the research starts at the nano-scale, it doesn’t stop there – the group builds and tests macroscale demonstrator devices based on our materials innovations.

Biography

Nick received a Master’s degree in Physics from the University of Warwick in 2004. Later in the same year he began a PhD at the University of Surrey. His research thesis investigated the effects of strain on dopants in silicon. In 2007 Nick joined Newcastle University as a Postdoctoral Researcher, continuing work on nano-scale doping of silicon- and germanium-based materials.

In 2009 he accepted a research position at Dublin City University, initially in a Postdoctoral Researcher position, before assuming a Lecturing role and leading two projects as Principal Investigator – the first on novel doping metrologies for nano-electronics/photovoltaics, and the second on silicon nano-pillars for thermoelectrics.

Since 2013 Nick has been Assistant Professor at Heriot-Watt University where he leads the Nano-Materials Lab (www.nanomaterialslab.com). His research aims to enhance the electronic, optical and thermal properties of silicon-based materials for applications in energy harvesting devices, such as photovoltaic cells or thermoelectric generators. He is also a Lecturer in Renewable Energy within Heriot-Watt’s School of Engineering & Physical Sciences.
