Light induced non-volatile switching of superconductivity in single layer FeSe on SrTiO3 substrate
Abstract
How photoexcitations influence superconductivity at the FeSe/SrTiO3 interface remains elusive. Here, the authors report fast optical generation of a metastable superconducting state and its reversal by voltage pulses at the FeSe monolayer/SrTiO3 interface.
