The School of Photovoltaic & Renewable Energy Engineering (SPREE) within the UNSW Faculty of Engineering has been at the leading edge of global solar cell development for over 30 years, reporting many world record solar cell efficiencies and furthering the development of a range of associated optoelectronic devices. Building on the recent demonstration of a hot carrier photovoltaic device  by the group of Associate Professor Nicholas Ekins-Daukes, This project (funded in part by the Australian Research Council) aims to develop a hot carrier photodetector with a paradigm shifting new capability: energy (or wavelength) resolving photodetection.
This project will consist of developing new hot carrier absorber materials with frustrated carrier cooling via slowed electron-phonon interactions, and processing those absorber materials into photodetectors with energy selective contacts followed by spectroscopic characterisation. The use of modelling will be required to understand the function of these new style of photodetector and demonstrate energy resolving photodetection. A focus will be on photodetection in both the visible and near infrared spectrum. For this project we are looking for outstanding PhD candidates who are interested in the areas of:
· Modelling of solid-state semiconductor optoelectronic devices
· Fabrication advanced photodiode devices in the III-V material system
· Both steady-state and ultrafast spectroscopy to study device and material properties
The supervisory team will consistent of Associate Professor Nicholas Ekins-Daukes, Dr Michael Nielsen, and Professor Gavin Conibeer. We will provide high-quality training for conducting scientific experiments and will ensure that our students develop a good understanding of semiconductor and material physics, sample fabrication, and spectroscopy. The project is suitable for applicants with a first degree in physics or engineering, and will benefit from a background in material and semiconductor physics. As this project will be a mix of theory, hands-on experimentation, and fabrication, we are looking for well-rounded students interested in learning a range of skills and who are motivated to find creative solutions to overcome unforeseen problems.
Please contact Dr Michael Nielsen (firstname.lastname@example.org) for further information. For your application please also attach the following documents: CV, academic transcript, and your motivation for doctoral studies. Please include how you feel your background potential aligns with the project.
