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…
Type-II Ising superconductivity and anomalous metallic state in macro-size ambient-stable ultrathin crystalline films
Yi Liu, Yong Xu, Jian Sun +13
Recent emergence of two-dimensional (2D) crystalline superconductors has provided a promising platform to investigate novel quantum physics and potential applications. To reveal es…
Edge states at nematic domain walls in FeSe films
Yonghao Yuan, Wei Li*, Bin Liu +9
Quantum spin Hall (QSH) effect is an intriguing phenomenon arising from the helical edge states in two-dimensional topological insulators. We use molecular beam epitaxy (MBE) to pr…
Superconductivity above 28 K in single unit cell FeSe films interfaced with GaO layer on NdGaO(110)
Haohao Yang, Guanyu Zhou, Yuying Zhu +12
We prepared single unit cell FeSe films on GaO terminated perovskite NdGaO(110) substrates and performed ex situ transport and scanning transmission electron microsco…
