Interface superconductivity in FeSe thin films on SrTiO_3grown by the PLD technique

In this study, we fabricate 5-30-nm-thick films of FeSe/STO using pulsed laser deposition (PLD). The grown films exhibit superconductivity with an onset T_{\mathrm{c}} that is much higher than that of bulk FeSe under ambient pressure. The observed T_{\mathrm{c}} values are exceptionally high in terms of the strain vs. T_{\mathrm{c}} relationship... Show more
