Research Associate in Materials Engineering

University of Bristol

About the Role

Applications are invited for the role of Postdoctoral Researcher at the Centre for Device Thermography and Reliability (CDTR), led by Professor Kuball. This role focuses on transforming thermal management and reliability of novel electronic semiconductor devices/chips, using wide and ultra-wide bandgap materials, such as GaN, Ga₂O₃, BN, AlN, and diamond.

Research areas include, for example, recycling of heat waste energy generated by the electronic chip, assessment of overall heat transport within the chips, their packaging, and systems. You will use new optical laser-based systems to study temperature and electric fields with sub-micron spatial resolution, which limit device performance and reliability.

New material and device structures will be designed and studied. Expertise in optical laser-based systems and thermal/thermomechanical simulations is beneficial. You will have the opportunity to study unique device structures, apply thermal imaging techniques for nm-scale devices, and access the extensive device testing suite available in Bristol, including advanced electrical, thermal, and electric field analysis of devices, and simulation tools (ATLAS, ANSYS).

You will collaborate within a 35-member team, with academic and industrial partners, and have the opportunity to make a major impact on future power device technology.

Research Context

The CDTR leads numerous UK and international strategic programmes on power and RF electronics, including:

• European Innovation Accelerator (part of Horizon Europe)
• CoolbrAIn programme
• EPSRC programme ULTRAlGaN
• UKRI Innovation and Knowledge Centre REWIRE

This position benefits from the Chair in Emerging Technologies awarded to Professor Kuball by the Royal Academy of Engineering (RAEng) and various US-funded programmes.

Key Responsibilities

• Conduct research to advance ultra-wide bandgap semiconductor device technology and understanding.
• Design, build, and use optical laser-based systems for device temperature and material thermal characterization.
• Develop material/device thermal models for device design using finite element and other simulation tools.
• Contribute to managing the thermal characterization laboratory and support short-term industrial contracts.

Candidate Requirements

• Postgraduate (PhD) experience in Physics, Materials Science, or Engineering, or working towards one, or equivalent professional qualification/experience.
• Ideally with a good publication record.
• Extensive expertise in semiconductor materials/devices, thermal characterization, and optical measurement techniques.
• Willingness to work collaboratively and co-supervise PhD students.

Employment Details

• Contract Type: Open-ended with fixed funding until 31/03/2028 (approx. 2 years from expected start date)
• Work Pattern: Full-Time, 35 hours per week
• Grade: I/Pathway 2
• Salary: £39,906 - £44,746 per annum
• School/Unit: School of Physics

Closing Date: 23:59 UK time on 18/01/2026
