“…At present, the materials that best satsify these requirements, and are commonly used for SNSPDs, are granular LTS such as NbN, NbTiN and WSi [12]. An alternative route would be to use HTS [20,21], in particular YBCO nanowires [2,[22][23][24][25][26], which could help realizing detectors that operate at higher temperatures. It is, however, challanging to use YBCO for SNSPDs.…”

“…Qualitatively, within the simplistic framework of the self-heating hotspot model [72], which has been even recently used to describe the IVC of NbN [26,73,74] and cuprate HTS [75,76] nanowires, the central part of the wire becomes normal due to Joule heating, producing a power equal to I • V . A cooling mechanism follows, via phonons and electron diffusion.…”

“…On the other hand, the high values of the thermal conductivity and of the Ginzburg-Landau parameter favor flux-flow behaviors, preventing selfheating effects, which could bring the nanostrips from the zero-voltage state directly to the normal state. In the context of HTSs, the observation of thermally hysteretic IVCs in ultrathin Pr 2−x Ce x CuO 4−δ (PCCO) nanostrips has been recently reported [22]. Recent research attention has been devoted to the realization of high critical current of ultrathin YBCO films [23], culminating with the observation of thermal hysteretic YBCO nanostrips IVCs [24].…”
