| Outline of Final Research Achievements |
We have theoretically investigated single-photon and biomolecular-ion detectors using superconducting nanostrips on the basis of the numerical simulation solving the time-dependent Ginzburg-Landau (TDGL) equations. We numerically verified that the hot-spot model without nucleation of vortices is adequate for ion detectors, whereas the vortex motion plays crucial roles for local normal transition of superconducting strips for single-photon detectors. Biomolecular-ion detectors using MgB2 superconducting nanostrips are thermally stable and have high detection efficiency. Furthermore, we have theoretically proposed a new single-photon detectors in which photon assisted vortices in superconducting nanostrips are detected by single-flux-quantum (SFQ) circuits.
