The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

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 …

Abstract A three-dimensional (3D) topological insulator (TI) is a quantum state of matter with
a gapped insulating bulk yet a conducting surface hosting topologically protected gapless …

We introduce an expression for the Z 2 topological invariant of band insulators using the non-
Abelian Berry connection. Our expression can identify the topological nature of a general …

Abstract van der Waals epitaxy (VDWE) is an ideal method for growing 2D materials and
topological insulators (TIs) onto a variety of substrates for heterostructure and integrated …

We report that Bi 2 Se 3 thin films can be epitaxially grown on SrTiO 3 substrates, which
allow for very large tunablity in carrier density with a back gate. The observed low field …

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 …

By intercalation of alkaline earth metal Sr in Bi2Se3, superconductivity with large shielding
volume fraction (∼ 91.5% at 0.5 K) has been achieved in Sr0. 065Bi2Se3. Analysis of the …

Recently, topological insulator materials have been theoretically predicted and
experimentally observed in both 2D and 3D systems. We first review the basic models and …
