In the recently discovered class of materials known as topological insulators, the presence of strong spin-orbit coupling causes certain topological invariants in the bulk to differ from their values in vacuum. The sudden change in invariants at the interface results in metallic, time reversal invariant surface states whose properties are useful for applications in spintronics and quantum computation. However, a key challenge is to fabricate these materials on the nanoscale appropriate for…

The changing colors of a quantum-confined topological insulator.
This work reports on catalyst-free, high-quality single-crystalline Bi2Se3 with controlled lateral sizes and layer thicknesses that could be tailored down to a few nanometers and a few quintuple layers (QLs), respectively, and suggests that while purely 2D sheets of few QL-thick Bi2 Se3 do exhibit small band gaps, the presently observed large gaps can only result from a combined effect of confinement in all three directions.

Experimental demonstration of topological surface states protected by time-reversal symmetry.
By studying the voltage-dependent standing wave patterns, the energy dispersion E(k) is determined, which confirms the Dirac cone structure of the topological states, and shows that, very different from the conventional surface states, backscattering of theTopological states by nonmagnetic impurities is completely suppressed.

Gate tunable infrared phonon anomalies in bilayer graphene.
It is suggested that the intensity growth and the softening originate from the coupling of the phonon mode to the narrow electronic transition between parallel bands of the same character, while the asymmetry is due to the interaction with the continuum of transitions between the lowest hole and electron bands.
