Electric field-induced superconducting transition of insulating FeSe thin film at 35 K
Electric field-induced superconducting transition of insulating FeSe thin film at 35 K
Significance One of the key strategies for obtaining higher superconducting critical temperature ( T c ) is to dope carriers into an insulator parent material with strong electron correlation. Here, we examined electrostatic carrier doping to insulator-like thin (∼10-nm-thick) FeSe epitaxial films using an electric double-layer transistor (EDLT) structure. The …
