What Makes the $T_c$ of FeSe/SrTiO${}_3$ so High ?

Abstract

This note reviews some of the recent progresses in the study of high temperature superconductivity in the interface between a single unit cell FeSe and SrTiO${}_3$. It offers the author's personal view of why $T_c$ is high and how to further increase it.
