Abstract

In this chapter, we introduce the electronic evidence of an insulator-superconductor crossover observed in the single-layer FeSe/SrTiO\(_3\) films. By measuring the electronic structure and energy gap, we have observed a clear evolution of an insulator to a superconductor with increasing carrier concentration. This insulator-superconductor crossover bears clear resemblance to that observed in various cuprates. These results suggest that the two-dimensionality and interfacial effect in this system have enhanced electron localization and/or correlation. They have provided not only a bridge connecting cuprates and iron-based superconductors but also a unique pathway toward finding new superconductors with a higher transition temperature.
