The proposed research aims to provide a complete understanding of extreme near-field thermal radiation by combining the sub-nm z -axis resolution of scanning probe microscopy (SPM) with optical detection of tip-scattering and thermal sensitivity of nanoheater/thermometer (NH/T) devices. Furthermore, to fundamentally understand how near-field radiation exchanges between the tip and underlying substrate, a closed-form model […]
