Structurally different from conventional oxide ferroelectrics with rigid lattices, van der Waals
(vdW) ferroelectrics have stable layered structures with a combination of strong intralayer …

The discovery and control of new phases of matter is a central endeavour in materials
research. The emergence of atomically thin 2D materials, such as transition-metal …

The successful isolation of phosphorene (atomic layer thick black phosphorus) in 2014 has
currently aroused the interest of 2D material researchers. In this review, first, the …

This review presents the state of the art in strain and ripple-induced effects on the electronic
and optical properties of graphene. It starts by providing the crystallographic description of …

Two-dimensional (2D) van der Waals ferroelectrics provide an unprecedented architectural
freedom for the creation of artificial multiferroics and nonvolatile electronic devices based on …

Low-dimensional multiferroic materials hold great promises in miniaturized device
applications such as nanoscale transducers, actuators, sensors, photovoltaics, and …

The state-of-the-art knowledge of ferroelectric and ferroelastic group-IV monochalcogenide
monolayers is surveyed. These semiconductors feature remarkable structural and …

We study the anisotropic electronic properties of two-dimensional (2D) SnS, an analogue of
phosphorene, grown by physical vapor transport. With transmission electron microscopy and …

Black phosphorus (BP), a typical mono-elemental and two-dimensional (2D) material, has
gathered significant attention owing to its distinct optoelectronic properties and promising …

We use a first-principles density functional theory approach to calculate the shift current and
linear absorption of uniformly illuminated single-layer Ge and Sn monochalcogenides. We …
