Coexistence of full-gap superconductivity and pseudogap in two-dimensional fullerides
Ming-Qiang Ren, Sha Han, Shu-Ze Wang +4
Alkali-fulleride superconductors with a maximum critical temperature Tc of 40 K exhibit similar electronic phase diagram with unconventional high-Tc superconductors where the super…
Visualizing molecular orientational ordering and electronic structure in CsnC60 fulleride films
Sha Han, Meng-Xue Guan, Can-Li Song +5
Alkali-doped fullerides exhibit a wealth of unusual phases that remain controversial by nature. Here we report a cryogenic scanning tunneling microscopy study of the sub-molecular…
Real-space observation of charge ordering in epitaxial La2-xSrxCuO4 films
Yang Wang, Yong Zhong, Zhiling Luo +9
The cuprate superconductors exhibit ubiquitous instabilities toward charge-ordered states. These unusual electronic states break the spatial symmetries of the host crystal, and hav…
Insulating Parent Phase and Distinct Doping Evolution to Superconductivity in Single-Layer FeSe/SrTiO3 Films
Yong Hu, Yu Xu, Yi-Min Zhang +19
The single-layer FeSe/SrTiO3 (FeSe/STO) films have attracted much attention because of their simple crystal structure, distinct electronic structure and record high superconducting…
Direct visualization of ambipolar Mott transition in cuprate CuO2 planes
Yong Zhong, Jia-Qi Fan, Ruifeng Wang +11
Identifying the essence of doped Mott insulators is one of the major outstanding problems in condensed matter physics and the key to understanding the high-temperature superconduct…
