A new laser-based imaging technique has been developed to study nanoscale heat and charge transport in ultrawide-bandgap semiconductors like diamond. By utilising a tabletop deep-ultraviolet (DUV) laser, researchers have achieved spatial resolutions of 287 nanometres, enabling detailed analysis of diamond’s transport behaviours. This breakthrough addresses the limitations of visible-light imaging methods and could revolutionise the … Read more
