The Hall conductivity $\sigma_{xy}$ of many condensed matter systems presents a step structure when a uniform perpendicular magnetic field is applied. We report the quantum Hall effect in buckled AB-bottom-top bilayer silicene and its robust dependence on the electronic valley and spin-orbit coupling. With the unique multi-valley electronic structure and the lack of spin degeneracy, the quantization of the Hall conductivity in this system is unlike the conventional sequence as reported for…

TLDR
This work provides a unique way to engineer discrete magnetoplasmon-like modes of AGNRs in the absence of magnetic field and finds them to be analogous to magnetoplasmons associated with collective excitations of Landau-quantized electrons.

Quantum Hall effect in twisted bilayer graphene.
TLDR
The measured Hall conductivity exhibits the same plateau values as for a commensurate Bernal bilayer, which implies that the eightfold degeneracy of the zero energy mode is topologically protected despite rotational disorder as recently predicted.
Silicene field-effect transistors operating at room temperature.
TLDR
A silicene field-effect transistor is reported, corroborating theoretical expectations regarding its ambipolar Dirac charge transport, with a measured room-temperature mobility of ∼100 cm(2) V(-1)‬s(-1), attributed to acoustic phonon-limited transport and grain boundary scattering.

TLDR
It is found that the Landau levels and magneto-transport properties of phosphorene under a perpendicular magnetic field within the framework of the effective k·p Hamiltonian and tight-binding model linearly depend both on the LL index n and magnetic field B, which is similar with that of conventional semiconductor two-dimensional electron gas.
