Topological insulators are new states of quantum matter which cannot be adiabatically
connected to conventional insulators and semiconductors. They are characterized by a full …

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 …

Two-dimensional (2D) materials exhibit a wide range of atomic structures, compositions, and
associated versatility of properties. Furthermore, for a given composition, a variety of …

In this paper we give the full microscopic derivation of the model Hamiltonian for the three-
dimensional topological insulators in the Bi 2 Se 3 family of materials (Bi 2 Se 3, Bi 2 Te 3 …

One of the fundamental properties of semiconductors is their ability to support highly tunable
electric currents in the presence of electric fields or carrier concentration gradients. These …

Topological insulators are predicted to present interesting surface transport phenomena but
their experimental studies have been hindered by a metallic bulk conduction that …

Abstract 2D materials are considered as intriguing building blocks for next‐generation
optoelectronic devices. However, their photoresponse performance still needs to be …

Long after the heady days of high‐temperature superconductivity, the oxides came back into
the limelight in 2004 with the discovery of the 2D electron gas (2DEG) in SrTiO3 (STO) and …

The topological insulator is a unique state of matter that possesses a metallic surface state of
massless particles known as Dirac fermions, which have coupled spin and momentum …
