An understanding of the aging and oxidation of the (0001) surface of Bi 2 Se 3 is critical to a
comprehensive physical picture of its topologically protected surface states. Here, the …

Although, the long-standing debate on the resistivity anomaly in ZrTe5 somewhat comes to
an end, the exact topological nature of the electronic band structure remains elusive till …

Topological insulators are a class of solids in which the non-trivial inverted bulk band
structure gives rise to metallic surface states,,,,, that are robust against impurity scattering …

We describe the topological surface states of Bi 4 Se 3, a compound in the infinitely adaptive
Bi 2-Bi 2 Se 3 natural superlattice phase series, determined by a combination of …

We report the emergence of a weak topological insulator (WTI), BiSe, of the Bi-chalcogenide
family with an indirect bandgap of 42 meV. Its structural unit consists of a bismuth bilayer (Bi …
