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...
متن کاملTopological 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...
متن کاملA 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...

متن کاملTopological 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 ...
