TL;DR: This work investigates the magneto-transport properties of Cr-doped Bi2(SexTe1-x)3 with different compositions under the effect of a gate voltage, and shows that a perpendicular electric field causes a shift in the electronic energy levels due to the Stark effect, which induces a topological quantum phase transition and, in turn, a magnetic phase transition.

Thermoelectric effects and topological insulators
TL;DR: The recent discovery of topological insulators (TIs) offers new opportunities for the development of thermoelectrics, because many TIs (such as Bi2Te3) are excellent thermolectric (TE) materials.

The electronic structure of ideal graphene
TL;DR: In this article, the authors present tight-binding description of the electronic structure of single-layer and multilayer graphene, with a special emphasis on emergence of massless Dirac fermions in honeycomb lattice, effects of trigonal warping, and symmetry protection of conical points in band structure.

Quantum spin Hall effect in graphene
Charles L. Kane,Eugene J. Mele +1 more
TL;DR: Graphene is converted from an ideal two-dimensional semimetallic state to a quantum spin Hall insulator and the spin and charge conductances in these edge states are calculated and the effects of temperature, chemical potential, Rashba coupling, disorder, and symmetry breaking fields are discussed.

New Method for High-Accuracy Determination of the Fine-Structure Constant Based on Quantized Hall Resistance
TL;DR: In this article, the Hall voltage of a two-dimensional electron gas, realized with a silicon metal-oxide-semiconductor field effect transistor, was measured and it was shown that the Hall resistance at particular, experimentally well-defined surface carrier concentrations has fixed values which depend only on the fine-structure constant and speed of light, and is insensitive to the geometry of the device.
