Biography:

I work with Dr. Rachel Oliver on the MACONS project funded by the ERC. The project aims to establish the direct relationship between defects and nanostructures (e.g. quantum dots) and their corresponding optical and electrical properties in nitride semiconductor materials. This involves a synergy of different microscopy techniques, ranging from CL-SEM, SCM, FIB, and TEM to APT, with the aim that exactly the same individual nanoscale feature will assessed in each technique. The study covers the interaction of defects with quantum wells grown on polar, semi-polar and non-polar planes, the segregation of dopants in p-type nitrides and the nanostructure of quantum dots. The achieved comprehensive understanding of the nanostructure, chemistry and properties of nitrides can be used to optimise fabrication processes, and thus to improve the device performance. The project is challenging but also fascinating.

We conduct world leading research into nitride based III-V semiconductors: material quality, characterisation and device development.

We are passionate about education and outreach! If you would like support for an education project then please .
