Ultrafast Spectroscopy of Novel Semiconductors and Devices UNSW Sydney in Australia

The School of Photovoltaic and Renewable Energy Engineering (SPREE) at the University of New South Wales (UNSW), Sydney, is internationally recognized as a leading research hub in photovoltaics and renewable energy. SPREE has played a pivotal role in the development and commercialization of advanced solar cell technologies, including the market-dominating ‘PERC’ design. The school’s research activities span novel processing techniques, advanced characterization, integration of silicon with new materials for multi-junction solar cells, and innovative concepts for next-generation energy devices.

This PhD project centers on the photophysics of novel semiconductors and devices, with a particular emphasis on the interactions between electrons/excitons and phonons/vibrational modes following photon absorption. Utilizing ultrafast spectroscopy—a technique employing femtosecond laser pulses—the project aims to unravel the electronic and vibrational dynamics in bulk semiconductor materials, interfaces, and optoelectronic devices. Ultrafast spectroscopy provides time-resolved insights into photoinduced processes, akin to strobe photography but at a billion-fold higher time resolution. The research also explores nonlinear optics for interface manipulation and characterization.

Key research topics include carrier and vibrational dynamics in perovskites, phonon cavities, second harmonic generation metrology of silicon interfaces, and laser-induced solar panel recycling. The project is highly interdisciplinary, drawing on physical chemistry, chemical engineering, energy technologies, nanotechnology, chemical physics, experimental physics, optical physics, solid-state physics, and semiconductor science.

Funding is available through the competitive UNSW RTPi scholarship, which provides a full scholarship for 3.5 years (covering university fees and a tax-free stipend of approximately AUD $39,206 per year). Additional support includes a conference attendance allowance and potential extra funding for outstanding candidates. Country-specific stipend schemes are available for students from India, Indonesia, China, Vietnam, Germany, Austria, and Chile. Domestic Australian students in good standing are eligible for fully funded positions.

Applicants should hold a Bachelor degree in Electrical Engineering, Physics, Chemistry, Materials Science, or a related discipline, with a minimum GPA of 80% or equivalent. Preference is given to candidates with a research-based Masters degree focused on materials, chemistry, or semiconductor physics, especially with experimental experience. Prior research experience is crucial for competitive international scholarships. Application materials should include a CV, academic transcript, and a motivation statement detailing your fit for the project.
