An archetypical layered topological insulator Bi 2 Se 3 becomes superconductive upon
doping with Sr, Nb or Cu. Superconducting properties of these materials in the presence of …

Robust massless Dirac states with helical spin textures were realized at the boundaries of
topological insulators such as van der Waals (vdW) layered Bi2Se3 family compounds …

We study how an inversion-breaking quantum critical point affects the ground state of a one-
dimensional electronic liquid with repulsive interaction and spin-orbit coupling. We find that …

In this study, we grew Cu co-doped single crystals of a topological superconductor
candidate Sr x Bi 2 Se 3, and studied their structural and transport properties. We reveal that …

We study surface states in the three-dimensional topological insulators Bi 2 Te 3− x Se x (x=
0, 2, 3) by polarization resolved resonant Raman spectroscopy. By tracking the spectral …

In this work, the role of Cu dopants in the development of superconductivity in B i 2 S e 3 is
investigated. A series of C ux B i 2 S e 3 (x= 0–0.3) crystals is grown using the Bridgman …

The tunability of the electronic topological transition is fundamentally important to unveil new
quantum matters. Here, we report the observation of pressure-induced electronic anomaly …

Abstract TI Sb 1.9 Cu 0.1 Te 3 is an ideal platform for investigating such semiconducting to
metal transition under extreme conditions. The unusual softening of two newly M1, M2 …

Abstract We grew Sr-doped Bi2Se3 thin films using molecular beam epitaxy, and their high
quality was verified using transmission electron microscopy. The thin films exhibited weak …

Structural, pressure-dependent resistivity, angle resolved photoemission spectroscopy
(ARPES), x-ray photoelectron diffraction (XPD) and band structure by DFT calculation have …
