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

Electrical charges on the boundaries of topological insulators favour forward motion over
back-scattering at impurities, producing low-dissipation, metallic states that exist up to room …

We propose a simple realization of the three-dimensional (3D) Weyl semimetal phase,
utilizing a multilayer structure, composed of identical thin films of a magnetically doped 3D …

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 …

We report on Raman spectroscopy of few quintuple layer topological insulator bismuth
selenide (Bi2Se3) nanoplatelets (NPs), synthesized by a polyol method. The as-grown NPs …

We study the weak antilocalization (WAL) effect in topological insulator Bi 2 Te 3 thin films at
low temperatures. The two-dimensional WAL effect associated with surface carriers is …

Topological insulators display unique properties, such as the quantum spin Hall effect,
because time-reversal symmetry allows charges and spins to propagate along the edge or …

Topological insulators exhibit a bulk energy gap and spin-polarized surface states that lead
to unique electronic properties,,,,,,,,, with potential applications in spintronics and quantum …

Bismuth selenide (Bi2Se3) is a topological insulator with metallic surface states (SS)
residing in a large bulk bandgap. In experiments, synthesized Bi2Se3 is often heavily n-type …

We study coherent electronic transport in charge-density-tunable microdevices patterned
from thin films of the topological insulator (TI) Bi 2 Se 3. The devices exhibit pronounced …
