we observed stable and boosted photocurrents upon resonant plasmonic excitation with
ultrathin SrTiO3 interfaces. This lattice matched inorganic perovskite between metal and Si can be initially functionalized as a conducting layer due to the nanofilament formation via soft dielectric breakdowntechnique. We verified the superior stability of devices incorporating a SrTiO3 layer by studying the photo-response, tunability and barrier height under high reverse biases.
