ARPES and MBE studies on the role of the interface in Monolayer FeSe on SrTiO3

ORAL

Abstract

Monolayer FeSe on SrTiO3 (STO) has been heavily studied in recent years due to the discovery of a large enhancement in its superconducting Tc compared to bulk FeSe, which is attributed to interfacial coupling between the film and substrate. To better understand this interface and how it leads to such a Tc enhancement, we reexamine this system by using MBE grown FeSe and STO coupled with in-situ synchrotron based angle-resolved photoemission spectroscopy (ARPES). Here we present the influence of different STO surface terminations and photon energy dependent ARPES results which help to clarify the role of the substrate in the monolayer FeSe system.
