This PhD project at the University of Bristol focuses on the development and application of ultrawide bandgap semiconductors for next-generation power circuits, aiming to power a green future. The research addresses the urgent need for improved efficiency in high voltage power conversion, which is critical for advancing electric transportation, renewable energy, and smart power distribution to reduce carbon emissions and combat climate change. As a student, you will design, fabricate, and characterize power electronic devices using ultrawide bandgap semiconductors, integrating them into power conversion circuits.

The project is highly interdisciplinary, involving both the Centre for Device Thermography and Reliability (CDTR) in the School of Physics and the School of Electrical, Electronic and Mechanical Engineering. This collaboration ensures a holistic approach, combining device and circuit design to maximize the real-world impact of these advanced materials. You will utilize advanced design tools to understand the underlying physics, innovate device designs, and perform fabrication and measurement in state-of-the-art cleanroom and electrical characterization labs.

The project also involves circuit design to demonstrate the suitability of these devices for next-generation green technologies, with the goal of mass-market implementation. The CDTR, with 35 research members, leads the £11M UKRI Innovation and Knowledge Centre REWIRE and participates in major European and ESA programmes. Supervision is provided by Dr. Matt Smith, with collaboration from Dr.

Jahdi, Prof. Kuball, Dr. Pomeroy, and Dr. Tang.

The Physics Graduate School at Bristol offers a vibrant, diverse community, comprehensive induction, targeted skills training, and strong support for career development. Funding covers full tuition, stipend, and training for home students, with limited fully-funded places for international students. Applicants need a strong background in physics or a related field and must meet English language requirements. The application deadline is 19 January 2026.
