Synthesis of Superconductor-Topological Insulator Hybrid Nanoribbon Structures
TL;DR: In this paper, the growth of the s-wave superconductor Sn on the topological insulator Bi2Te3 by physical vapor transport has been studied, and two types of structures are formed: Sn nanoparticles, that cover Bi 2Te3 plates and belts in a cloud-like shape, and thin Sn layers on Bi 2TE3 plates, that appear in puddle-like recessions.

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.
