Research Projects

We are looking for someone with strong computing/modelling skills to undertake a PhD on the growth of dislocations in optoelectronic semiconductor devices. For example, he image below shows the dendritic growth of a single dislocation across the optical aperture of a vertical-cavity surface emitting laser (VCSEL) like the one you have in your computer mouse. There is currently no model of how this happens!

Failed VCSEL

I am also working on the use of digitally-reconstructed large-angle electron diffraction patterns to solve and refine crystal structures.

Simulated LACBED patterns from Ca3Mn2O7
