Silicene, a silicon analogue of graphene, has attracted increasing attention during the past
few years. As early as in 1994, the possibility of stage corrugation in the Si analogs of …

The concept of topological energy bands and their manifestations have been demonstrated
in condensed matter systems as a fantastic paradigm toward unprecedented physical …

Topological phases with insulating bulk and gapless surface or edge modes have attracted
intensive attention because of their fundamental physics implications and potential …

This article reviews the theoretical and experimental work related to the electronic properties
of bilayer graphene systems. Three types of bilayer stackings are discussed: the AA, AB, and …

Over a long period of exploration, the successful observation of quantized version of
anomalous Hall effect (AHE) in thin film of magnetically doped topological insulator (TI) …

Silicene is a monolayer of silicon atoms forming a two-dimensional honeycomb lattice,
which shares almost every remarkable property with graphene. The low-energy structure of …

We propose realizing the quantum anomalous Hall effect by proximity coupling graphene to
an antiferromagnetic insulator that provides both broken time-reversal symmetry and spin …

Two-dimensional (2D) ferrovalley materials, displaying coexistence of spontaneous spin
and valley polarizations, have recently attracted significant attention due to their potential for …

Graphene exhibits superior mechanical strength, high thermal conductivity, strong light–
matter interactions, and, in particular, exceptional electronic properties. These merits make …

We find theoretically a new quantum state of matter—the valley-polarized quantum
anomalous Hall state in silicene. In the presence of Rashba spin-orbit coupling and an …
