The scaling of complementary metal–oxide–semiconductor (CMOS) technology is
increasingly challenging, but demand for low-power data storage and processing continues …

The first-principles band theory paradigm has been a key player not only in the process of
discovering new classes of topologically interesting materials, but also for identifying salient …

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 …

Boosted by the great success of graphene, the past decade has witnessed the rapid
development of graphene-analogous two-dimensional (2D) nanomaterials. Despite the high …

Quantum systems in confined geometries are host to novel physical phenomena. Examples
include quantum Hall systems in semiconductors and Dirac electrons in graphene. Interest …

Abstract 2D materials have attracted considerable attention in the past decade for their
superlative physical properties. These materials consist of atomically thin sheets exhibiting …

The study of topological insulators has generally involved search of materials that have this
property as an innate quality, distinct from normal insulators. Here we focus on the possibility …

While theoretical studies predicted the stability and exotic properties of plumbene, the last
group‐14 cousin of graphene, its realization has remained a challenging quest. Here, it is …

Inspired by the great development of graphene, more and more research has been
conducted to seek new two-dimensional (2D) materials with Dirac cones. Although 2D Dirac …

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 …
