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

In the ever-increasing energy demand scenario, the development of novel photovoltaic (PV)
technologies is considered to be one of the key solutions to fulfil the energy request. In this …

BACKGROUND Materials by design is an appealing idea that is very hard to realize in
practice. Combining the best of different ingredients in one ultimate material is a task for …

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 …

Ferroelectricity usually fades away as materials are thinned down below a critical value. We
reveal that the unique ionic-potential anharmonicity can induce spontaneous in-plane …

We predict enormous, anisotropic piezoelectric effects in intrinsic monolayer group IV
monochalcogenides (MX, M= Sn or Ge, X= Se or S), including SnSe, SnS, GeSe, and GeS …

Phosphorene and phosphorene analogues such as SnS and SnSe monolayers are
promising nanoelectronic materials with desired bandgap, high carrier mobility, and …

The family of 2D and layered materials has been expanding rapidly for more than a decade.
Within this large family of hundreds of materials, black phosphorus and its isoelectronic …

Abstract 2D layered materials such as graphene, black phosphorus (BP), transition metal
dichalcogenides (TMDCs), and their hybrid systems exhibit wide coverage of bandgaps …

Two-dimensional graphene-based van der Waals heterostructures have received
considerable interest because of their intriguing characteristics compared with the …
