Dr James Pomeroy

Research summary

My main research interest is the application of optical spectroscopy to study the properties of III-nitride and boron-rich semiconductors, and devices based on these materials.

I also have an interest in electrical methods for device characterisation.

My previous work has included InN, B12As2 and AlGaN/GaN field effect transistors. Currently, I am helping to develop a novel time-resolved measurement technique for studying self-heating and other transient phenomena in electronic devices. We have been able to achieve sub-micron spatial resolution and nanosecond temporal resolution.
