Researchers at the University of Connecticut are making smart moves in tracking heat in advanced semiconductors. By working with ultrawide bandgap (UWBG) materials like gallium oxide and diamond—known for their robustness under high voltage and temperature—they’re addressing one of the trickier aspects of modern electronics: how to measure heat with pinpoint accuracy.
Steered by Ph.D. candidates in collaboration with the U.S. Naval Research Laboratory, the team’s findings, featured in Applied Physics Letters, explore techniques such as optical thermoreflectance and electrical methods for precise thermal measurements. If you’ve ever grappled with overheating issues in tech, you’ll appreciate how these approaches could help manage heat more efficiently in devices across energy, healthcare, and communications.
As components continue to shrink while packing more power, keeping track of localised heating is essential. This study not only deepens our understanding of thermal challenges but also offers practical insights to drive the commercialisation of UWBG devices in high-tech industries.
