Substrate Engineering of Monolayer FeSe Films

ORAL

Abstract

Monolayer FeSe films will exhibit various properties on different substrates: the superconducting transition temperature (Tc) is suppressed if we choose graphene as the substrate, while SrTiO3 abd TiO2 substrates can boost the Tc to ~60 K. In this talk, we present the systematic tuning of the substrate structure, and the resulting change in the properties of FeSe, using a combined in-situ system of oxide MBE, chalcogenide MBE, STM and ARPES.
