ROBUST TRANSPORT OF QUANTUM SPIN HALL STATE IN HgTe/CdTe QUANTUM WELL
TL;DR: In this paper, the effect of nonmagnetic scattering potential at the edge of the quantum well on transport properties of the system was investigated and the results obtained with the help of the Green's function technique suggest that the transport of the QSH state is indeed a robust one where the conductivity takes a constant value independent of the number, shape, strength or length of the scattering potential.

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.
