ABSTRACT The two-dimensional (2D) magnet, a long-standing missing member in the
family of 2D functional materials, is promising for nextgeneration information technology …

BACKGROUND The electron can be considered as a tiny magnet, with two opposite poles
defining its magnetic field associated with the spin and orbital motion. When such minuscule …

Ferroelectricity in ultrathin two-dimensional (2D) materials has attracted broad interest due
to potential applications in nonvolatile memory, nanoelectronics and optoelectronics …

The realization of long-range ferromagnetic order in two-dimensional van der Waals
crystals, combined with their rich electronic and optical properties, could lead to new …

The isolation of graphene in 2004 from graphite was a defining moment for the “birth” of a
field: two-dimensional (2D) materials. In recent years, there has been a rapidly increasing …

Abstract Two-dimensional (2D) magnetism with a high Curie temperature (T c) has been the
pursuit of generations for its potential application in spintronic devices. Meanwhile, some …

Intrinsically ferromagnetic 2D semiconductors are essential and highly sought for nanoscale
spintronics, but they can only be obtained from ferromagnetic bulk crystals, while the …

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 …

Piezoelectricity is a unique material property that converts mechanical energy into electricity
or vice versa. Starting from the group-III monochalcogenide monolayers, we design a series …

Atomically thin two-dimensional (2D) materials have received considerable research interest
due to their extraordinary properties and promising applications. Here we predict the …
