Abstract 2D materials are considered to be the most promising materials for photodetectors
due to their unique optical and electrical properties. Since the discovery of graphene, many …

Bismuth telluride is the working material for most Peltier cooling devices and thermoelectric
generators. This is because Bi2Te3 (or more precisely its alloys with Sb2Te3 for p‐type and …

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

Topological insulators represent a new quantum state of matter which is characterized by
peculiar edge or surface states that show up due to a topological character of the bulk wave …

The optoelectronic properties of bismuth oxyhalides have led to their utility in applications
such as pigments in the cosmetics industry, 1, 2 pharmaceuticals, 3, 4 phosphors, 5 gas …

Tetradymites are M 2 X 3 compounds—in which M is a group V metal, usually Bi or Sb, and
X is a group VI anion, Te, Se or S—that crystallize in a rhombohedral structure. Bi 2 Se 3, Bi …

We report successful spin injection into the surface states of topological insulators by using a
spin pumping technique. By measuring the voltage that shows up across the samples as a …

We report the synthesis and photoelectrochemical assessment of phase pure tetragonal
matlockite structured BiOX (where X= Cl, Br, I) films. The materials were deposited using …

The van der Waals compound, MnBi 2 Te 4, is the first intrinsic magnetic topological
insulator, providing a materials platform for exploring exotic quantum phenomena such as …

Although the richness of spatial symmetries has led to a rapidly expanding inventory of
possible topological crystalline (TC) phases of electrons, physical realizations have been …
