Direct observation of high temperature superconductivity in one-unit-cell FeSe films
Wenhao Zhang, Yi Sun, Jinsong Zhang +26
Heterostructure based interface engineering has been proved an effective method for finding new superconducting systems and raising superconductivity transition temperature (TC). I…
Crossover between Weak Antilocalization and Weak Localization of Bulk States in Ultrathin Bi2Se3 Films
Huichao Wang, Haiwen Liu, Cui-Zu Chang +9
We report transport studies on the 5 nm thick Bi2Se3 topological insulator films which are grown via molecular beam epitaxy technique. The angle-resolved photoemission spectroscopy…
Imaging the Electron-Boson Coupling in Superconducting FeSe
Can-Li Song, Yi-Lin Wang, Ye-Ping Jiang +7
Scanning tunneling spectroscopy has been used to reveal signatures of a bosonic mode in the local quasiparticle density of states of superconducting FeSe films. The mode appears be…
