The great success of graphene has boosted intensive search for other single-layer thick
materials, mainly composed of group-14 atoms arranged in a honeycomb lattice. This new …

We propose a new family of the d 0 orbital XY (X= K, Rb, Cs; Y= N, P, As, Sb, Bi) monolayers
with abundant and novel topology and valley properties. The KN, RbN, RbP, RbAs, CsP …

Since the first realisation of the quantum anomalous Hall effect (QAHE) in a dilute magnetic-
doped topological insulator thin film in 2013, the quantisation temperature has been limited …

Recently, the discovery of intriguing properties in intrinsic two dimensional ferromagnetism
has spurred huge interest in investigating their applications in spintronics. Here, we predict …

We analyze the detailed structure of topological edge mode protection occurring in
hexagonal quantum spin Hall (QSH) materials. We focus on bismuthene, antimonene, and …

Meeting of non-trivial topology with magnetism results in novel phases of matter, such as
quantum anomalous Hall (QAH) or axion insulator phases. Even more exotic states with …

Abstract Two-dimensional (2D) magnets have broad application prospects in the spintronics,
but how to effectively control them with a small electric field is still an issue. Here we propose …

We investigate the physical properties of silicene with both staggered sublattice potential
and magnetization by using Kubo formalism, the latter arises from the magnetic proximity …

The quantum anomalous Hall (QAH) effect has attracted enormous attention since it can
induce topologically protected conducting edge states in an intrinsic insulating material. For …
