Self-Heating Hotspots in Superconducting Nanowires Cooled by Phonon Black-Body Radiation

Abstract: Controlling thermal transport is important for a range of devices and technologies, from phase change memories to next-generation electronics. This is especially true in nano-scale devices where thermal transport is altered by the influence of surfaces and changes in dimensionality. In superconducting nanowire single-photon detectors, the thermal boundary conductance (TBC) between the nanowire and the substrate it is fabricated on influences most of the performance metrics that make these detectors attractive … Show more

“…The hot-spot characteristics are a crucial part of a WL employed as a detector. The former requires cooling down via a thermal relaxation process to come back to the initial superconducting state and subsequently detect the next signal [64][65][66][67] . This determines the resetting time of the device, the resolution (frequency) of the detection and, thus, the efficiency 10 .…”
