Postgraduate Researcher (Metamaterials CDT 2014)
I am a final year postgraduate researcher investigating the electronic properties of the thinnest known materials and stacks of these materials, which are known as van der Waals heterostructures. More specifically, the project explores their potential applications in light detection or generation.
Graphene, a single layer of carbon atoms, is one example of such a material and has electrical properties comparable to those of copper. Other materials include transition metal dichalcogenides (TMDs), which behave in a manner similar to the silicon found in modern day computers and cameras.
These materials have the potential to replace the current state of the art, bringing with them additional benefits due to their atomically thin nature. Their high mechanical strength and flexibility means that future generations of cameras, touch screens and computing chips can be incorporated into wearable electronics or readily installed in previously challenging environments.
In 2014 I graduated with a Masters of Physics (MPhys) from Exeter. During my masters project I worked on producing graphene inks from the chemical exfoliation of bulk graphite. These inks hold the potential to be utilized as transparent conductive films, replacing current transparent conductors such as ITO (Indium Tin Oxide), which would bring several advantages. These include a cheaper and more environmentally friendly production method (from using Carbon over the rare-earth metal Indium) and the increased flexibility desirable for modern devices.
