Direct Observation of High-Temperature Superconductivity in One-Unit-Cell FeSe Films
Direct Observation of High-Temperature Superconductivity in One-Unit-Cell FeSe Films
Heterostructure based interface engineering has been proved an effective method for finding new superconducting systems and raising superconductivity transition temperature (TC). In previous work on one unit-cell (UC) thick FeSe films on SrTiO3 (STO) substrate, a superconducting-like energy gap as large as 20 meV, was revealed by in situ scanning …
