In this work, we report the growth of high-quality BiSe thin films deposited on Si (111) substrates at different temperatures via pulsed laser deposition. We observe poor sample quality at a low substrate temperature (T[Formula: see text]C), and as t

WTe2, a type-II Weyl semimetal, has recently attracted much attention due to its unique band structure leading to extremely large magnetoresistance and exceedingly high mobility. In this report, we discuss the signature of Lifshitz transition in WTe2

Weak topological insulators (TIs) host non-trivial topological surface state bands (SSBs) at the side surface of the crystal while the top (001) surface can be topologically either dark or light. In our detailed angle-resolved photoelectron spectrosc

Weak topological insulators are elusive topological materials that were subjected to relatively few experimental studies in the past owing to the lack of stable systems. Here, a detailed investigation of the low-temperature electrical transport on Bi

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-2), a known quantum spin hall insulator sandwiched between tw

We present a comparative angle resolved photoelectron spectroscopy (ARPES) study on Bi2Se3 and BiSbTe1.25Se1.75. Dirac like surface state bands (SSB) and effects of band bending (BB) are observed in both the compounds. The BB effects are more pronoun

Granular conductors form an artificially engineered class of solid state materials wherein the microstructure can be tuned to mimic a wide range of otherwise inaccessible physical systems. At the same time, topological insulators (TIs) have become a
