The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

In this paper, we review recent progress on colloidal growth of 2D nanocrystals. We identify
the four main sources of anisotropy which lead to the formation of plate-and sheet-like …

Indium phosphide (InP) colloidal quantum dots (QDs) have been drawn significant attention
as a potentially less toxic alternative to cadmium-based QDs over the past two decades. The …

The past decade has witnessed the emergence of a new frontier in condensed matter
physics: topological materials with an electronic band structure belonging to a different …

Topological insulators demonstrate tremendous potential in fields of electronics and
magnetism for their unique boundary states that are topologically protected against …

We discuss the ultrafast evolution of the surface electronic structure of the topological
insulator Bi2Te3 following a femtosecond laser excitation. Using time and angle-resolved …

Despite their huge application capabilities, millimeter‐and terahertz‐wave photodetectors
still face challenges in the detection scheme. Topological insulators (TIs) are predicted to be …

Topological insulators (TIs) have an insulating bulk but a metallic surface. In the simplest
case, the surface electronic structure of a three-dimensional (3D) TI is described by a single …

Thin films of V–VI compound semiconductors (Bi2Se3, Bi2Te3 and Sb2Te3) have been
synthesized recently as three‐dimensional topological insulators (TIs). Although these …

Abstract Infrared (IR) detection at 1300–1650 nm (optical communication waveband) is of
great significance due to its wide range of applications in commerce and military. Three …
