Fe-vacancy ordered Fe4Se5: The insulating parent phase of FeSe superconductor
Keng-Yu Yeh, Yan-Rai Chen, Tung-Sheng Lo +4
We have carried out a detailed study to investigate the existence of an insulating parent phase for FeSe superconductor. The insulating Fe4Se5 with specific Fe-vacancy order shows…

Possible Topological Phase Transition in Fe-Vacancy-Ordered -FeSe Nanowires
Keng-Yu Yeh, Tung-Sheng Lo, Chung-Chieh Chang +4
We studied the electrical transport on -FeSe single-crystal nanowires, exhibiting Fe-vacancy order and mixed valence of Fe. We observed a…

Observation of Collective Coulomb Blockade in a Gate-controlled Linear Quantum-dot Array
Wen-Yao Wei, Tung-Sheng Lo, Chiu-Chun Tang +8
The quantum transport of electrons in an artificial atom, such as a quantum dot (QD), is governed by the Coulomb blockade (CB) effects, revealing the ground-state charge configurat…
