Observation of time-reversal-protected single-dirac-cone topological-insulator states in Bi2Te3 and Sb2Te3.

We show that the strongly spin-orbit coupled materials Bi2Te3 and Sb2Te3 and their derivatives belong to the Z2 topological-insulator class. Using a combination of first-principles theoretical calculations and photoemission spectroscopy, we directly show that Bi2Te3 is a large spin-orbit-induced indirect bulk band gap (delta approximately 150 meV) semiconductor whose surface is characterized by...

Topological insulator with time-reversal symmetry

It is impossible to have quantum Hall effect without breaking the time-reversal symmetry. xy  xy. If we want xy to be invariant under , xy  xy, xy must be zero. Q: Can we have other type of topological insulators, in the presence of -symmetry? By saying topological insulator, I mean an insulator with a protected metallic edge. By protected, I mean no matter what we do, we cannot tu...

A natural topological insulator.

The earth's crust and outer space are rich sources of technologically relevant materials which have found application in a wide range of fields. Well-established examples are diamond, one of the hardest known materials, or graphite as a suitable precursor of graphene. The ongoing drive to discover novel materials useful for (opto)electronic applications has recently drawn strong attention to to...

Topological insulator nanostructures

© 2014 Materials Research Society MRS BULLETIN • VOLUME 39 • OCTOBER 2014 • www.mrs.org/bulletin Introduction Topological insulators (TIs) are a class of materials where the bulk is a band insulator, but the surface possesses electronic states carrying electric current. 1 , 2 One unique characteristic of the surface bands is the spin-momentum locking property—electrons have a single spin state ...
