Abstract Since penta-graphene (PG), a two-dimensional (2D) carbon allotrope exclusively
composed of five-membered rings, was proposed in 2015, a great deal of effort has been …

Two-dimensional (2D) materials exhibit diverse properties, such as auxetic properties,
magnetism, excellent photocatalytic performance, and unique piezoelectric response …

Discovery of new two-dimensional (2D) materials not only has important fundamental
research significance but also has promising application prospects. Through systematic …

Two-dimensional (2D) materials with negative Poisson's ratios (NPRs) hold tremendous
potential in diverse electronic devices. However, most 2D auxetic materials exhibit small out …

Pentagonal two-dimensional ternary sheets are an emerging class of materials because of
their novel characteristic and wide range of applications. In this work, we use first-principles …

The photogalvanic effects (PGEs) in low-dimensional devices were thought to be an
important mechanism to generate pure spin current which was a essential problem in …

Abstract Two-dimensional (2D) auxetic properties and ferromagnetism are two major
focuses of research for next-generation nanomechanical and spintronic devices. However …

Here we propose a type of ferromagnetic semiconductors: ferromagnetic negative charge-
transfer energy insulator (FNCTEI). In FNCTEI, the negative charge-transfer states strongly …

Geometrical variations in a particular structure or other mechanical factors are often cited as
the cause of a negative Poisson's ratio (NPR). These factors are independent of the …

The commercialization process of lithium-sulfur batteries (LISBs) is hindered by several
problems, including low electroconductivity, the dissolution of lithium polysulfides (LiPSs) …
