Universal superconductivity phase diagram for pressurized tetradymite topological insulators
Shu Cai, S. K. Kushwaha, Jing Guo +13
We show that two different superconducting phases exist at high pressures in the optimized tetradymite topological insulators Bi2Te2Se (BTS) and Bi1.1Sb0.9Te2S (BSTS). The supercon…

Independence of topological surface state and bulk conductances in three-dimensional topological insulators
Shu Cai, Jing Guo, Vladimir A. Sidorov +12
The archetypical 3D topological insulators Bi2Se3, Bi2Te3 and Sb2Te3 commonly exhibit high bulk conductivities, hindering the characterization of the surface state charge transport…

Zero resistance from one atmosphere to the pressure of earth's outer core in a superconducting high entropy alloy
Jing Guo, Honghong Wang, Fabian von Rohr +9
We report the observation of extraordinarily robust zero-resistance superconductivity in the pressurized (TaNb)0.67(HfZrTi)0.33 high entropy alloy - a new kind of material with a b…
