Orbital-dependent modulation of the superconducting gap in uniaxially strained BaKFeAs
L. Chen, T. T. Han, C. Cai +4
Pairing symmetry which characterizes the superconducting pairing mechanism is normally determined by measuring the superconducting gap structure (). Here, we report the meas…
Metal-Insulator Transition and Emergent Gapped Phase in the Surface-Doped 2D Semiconductor 2H-MoTe
T. T. Han, L. Chen, C. Cai +4
Artificially created two-dimensional (2D) interfaces or structures are ideal for seeking exotic phase transitions due to their highly tunable carrier density and interfacially enha…
Revealing the intrinsic superconducting gap anisotropy in surface-neutralized BaFe(AsP)
Ziming Xin, Yudi Wang, Cong Cai +4
Alkaline-earth iron arsenide (122) is one of the most studied families of iron-based superconductors, especially for angle-resolved photoemission spectroscopy. While extensive phot…
Doping-controlled transition from excitonic insulator to semimetal in TaNiSe
L. Chen, T. T. Han, C. Cai +4
Excitonic insulator (EI) is an intriguing insulating phase of matter, where electrons and holes are bonded into pairs, so called excitons, and form a phase-coherent state via Bose-…
Band insulator to Mott insulator transition in 1T-TaS
Y. D. Wang, W. L. Yao, Z. M. Xin +6
1T-TaS undergoes successive phase transitions upon cooling and eventually enters an insulating state of mysterious origin. Some consider this state to be a band insulator with…
Isostructural spin-density-wave and superconducting gap anisotropies in iron-arsenide superconductors
T. T. Han, L. Chen, C. Cai +4
When passing through a phase transition, electronic system saves energy by opening energy gaps at the Fermi level. Delineating the energy gap anisotropy provides insights into the…
