 note = {We report the fabrication and photoresponse of 5nm thick La1.85Sr0.15CuO4 nanostrip with a width of 100nm. The I-V characteristics of the nanostrip show a hysteresis and a sharp voltage jump at Ic. The Jc(3K) of the nanostrip is 2.3 × 107 A/cm2. The nanostrip exhibits photoresponse signals when illuminated by a pulse laser at 1560 nm wavelength with a bias current just below Ic. The height of the signal reduces as the optical intensity decreases and disappears below -10 dBm. The signal also decreases as the temperature increases, but it exists up to 30 K. These results suggest the possibility of La1.85Sr0.15CuO4 nanostrip as single-photon detector (SSPD, SNSPD) working at high temperature by further reducing the cross-section of the strip.},
