Martin Kuball

A fully funded PhD studentship is available for 2025-2026, focusing on the development of high power radio frequency (RF) semiconductor devices based on Gallium Oxide (Ga2O3). The project addresses the critical challenge of thermal management in Ga2O3 RF power devices, which are essential for applications in defence, aerospace, science, medicine, and industrial heating. The research will involve innovative approaches such as integrating microfluidics and diamond heat spreaders to improve device efficiency and reliability. The position is a collaboration between the University of Bristol (UK), which offers expertise in Ga2O3 growth and material characterization, and Imec (Belgium), known for RF device fabrication and testing. Applicants should have excellent academic records from leading universities and a background in materials science, electrical engineering, physics, or related disciplines. The studentship provides an opportunity to work in a cutting-edge research environment with access to advanced facilities and international collaboration. Interested candidates should contact Professor Martin Kuball or apply through the provided link. The application deadline is December 28, 2024.

The University of Bristol's CDTR is offering two PhD opportunities focused on developing next-generation power semiconductor technologies. These positions involve designing and building new power converter circuits using ultrawide bandgap semiconductor device building blocks, such as AlGaN, AlN, and diamond. The research aims to create clean and efficient high voltage devices for applications in electric transportation, renewable energy, and power grids, contributing to a sustainable future. Successful candidates will gain hands-on experience in material growth, device fabrication, and advanced performance and reliability characterization. The projects are supervised by Matthew Smith, Dr. Saeed Jahdi, and Prof. Martin Kuball, and are supported by the REWIRE-IKC team. Students will benefit from world-class facilities, industry collaboration, and a vibrant research community. The positions offer training in skills highly valued across the semiconductor sector. Applicants should have a relevant background in electrical engineering, materials science, or physics, and a strong interest in power electronics and clean energy technologies. Funding details are not specified, but the opportunities are competitive and well-supported. Interested candidates are encouraged to apply via the provided links and contact the supervisors with any questions.
