TLDR
FeSe/STO is confirmed as an ideal material for studying high-Tc superconductivity by means of in situ four-point probe electrical transport measurements, and rekindle the long-standing idea that electron pairing at interfaces between two different materials can be tailored to achieve high-temperaturesuperconductivity.Abstract:
Monolayer iron selenide grown on SrTiO3 has recently gained attention due to suggestive evidence it superconducts at high temperature. In situ electrical transport measurements now reveal a transition temperature above 100 K.read more
