Unraveling Enhanced Superconductivity in Single-layer FeSe through Substrate Surface Terminations
Qiang Zou, Gi-Yeop Kim, Jong-Hoon Kang +7
Single-layer FeSe films grown on (001) SrTiO3 substrates have shown a significant increase in superconducting transition temperature compared to bulk FeSe. Several mechanisms have…
