The focus of my PhD is to probe the interface of power semiconductor heterostructures using a combination of soft and hard X-ray photoelectron spectroscopy (XPS). In particular, I am interested in using the dual XPS approach to study the interaction of adjacent metallisation layers in the stack, namely a titanium-tungsten diffusion barrier and copper metallisation. The majority of my experiments are conducted at synchrotron facilities in order for me to conduct measurements in the hard X-ray regime. My two favourite facilities are the Diamond Light Source here in the UK and PETRA III in Hamburg.
