Observation of superconductivity in pressurized Weyl semimetal candidate TaIrTe4
Shu Cai, Eve Emmanouilidou, Jing Guo +7
Here we report the observation of superconductivity in pressurized type-II Weyl semimetal (WSM) candidate TaIrTe4 by means of complementary high-pressure transport and synchrotron…

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…
