Title: Light induced non-volatile switching of superconductivity in single layer FeSe on SrTiO 3 substrate

Abstract

The capability of controlling superconductivity by light is highly desirable for active quantum device applications. Since superconductors rarely exhibit strong photoresponses, and optically sensitive materials are often not superconducting, efficient coupling between these two characters can be very challenging in a single material. Here we show that, in FeSe/SrTiO 3 heterostructures, the superconducting transition temperature in FeSe monolayer can be effectively raised by the interband photoexcitations in the SrTiO 3 substrate. Attributed to a light induced metastable polar distortion uniquely enabled by the FeSe/SrTiO 3 interface, this effect only requires a less than 50 μWcm -2 continuous-wave light field. The fast optical generation of superconducting zero resistance state is non-volatile but can be rapidly reversed by applying voltage pulses to the back of SrTiO 3 substrate. The capability of switching FeSe repeatedly and reliably between normal and superconducting states demonstrate the great potential of making energy-efficient quantum optoelectronics at designed correlated interfaces.

Scanning tunneling microscope (STM) topography images of sample with and without FeTe capping layer are shown on the right. Scale bars indicate 100 nm.more » b Solid lines: sample resistances measured in dark (black) and under UV illumination (red), showing an increase in TC from 24 K to 30 K. Dashed lines plot the resistances measured with 9 T out-of-plane magnetic field. c Resistances measured at different UV intensities. Despite of the greater normal state resistance modulations at larger light intensities, the TC enhancement is intensity independent« less
