Electronic structure of the ingredient planes of cuprate superconductor Bi2Sr2CuO6+δ: a comparison study with Bi2Sr2CaCu2O8+δ
Yan-Feng Lv, Wen-Lin Wang, Hao Ding +13
By means of low-temperature scanning tunneling microscopy, we report on the electronic structures of BiO and SrO planes of Bi2Sr2CuO6+δ (Bi-2201) superconductor prepared by argon-i…
Kondo-like zero-bias conductance anomaly in a three-dimensional topological insulator nanowire
Sungjae Cho, Ruidan Zhong, John Schneeloch +2
Zero bias anomalies in topological nanowires have recently captured significant attention, as they are possible signatures of Majorana modes. Yet there are many other possible orig…
Mapping the Electronic Structure of Each Ingredient Oxide Layer of High- Cuprate Superconductor Bi2Sr2CaCu2O8+δ
Yan-Feng Lv, Wen-Lin Wang, Jun-Ping Peng +11
Understanding the mechanism of high transition temperature (Tc) superconductivity in cuprates has been hindered by the apparent complexity of their multilayered crystal structure.…
Fully gapped superconductivity in In-doped topological crystalline insulator PbSnTe
Guan Du, Zengyi Du, Delong Fang +5
Superconductors derived from topological insulators and topological crystalline insulators by doping have long been considered to be candidates as topological superconductors. Pb$_…
Energy dissipation in the time domain governed by bosons in a correlated material
J. D. Rameau, S. Freutel, M. A. Sentef +13
In complex materials various interactions play important roles in determining the material properties. Angle Resolved Photoelectron Spectroscopy (ARPES) has been used to study thes…
Dependence of superconductivity in CuxBi2Se3 on quenching conditions
J. A. Schneeloch, R. D. Zhong, Z. J. Xu +2
Topological superconductivity, implying gapless protected surface states, has recently been proposed to exist in the compound CuxBi2Se3. Unfortunately, low diamagnetic shielding fr…
Surface-state-dominated transport in crystals of the topological crystalline insulator In-doped PbSnTe
Ruidan Zhong, Xugang He, John A. Schneeloch +8
Three-dimensional topological insulators and topological crystalline insulators represent new quantum states of matter, which are predicted to have insulating bulk states and spin-…
Substitution of Ni for Fe in superconducting FeTeSe depresses the normal-state conductivity but not the magnetic spectral weight
Jinghui Wang, Ruidan Zhong, Shichao Li +12
We have performed systematic resistivity and inelastic neutron scattering measurements on FeNiTeSe samples to study the impact of Ni substitution on…
