We review layered and ultrathin electrides with exciting properties like high electrical mobility, high carrier concentrations, and low work functions.

The merging of the materials science paradigms of liquid crystals and 2D materials promises superb new opportunities for the advancement of the fields of optoelectronics and photonics. In this review, we summarise the development and applications of 2D material liquid crystals for optoelectronics and photonics.

The incorporation of graphene, TMDCs, insulating hBN and their hybrid systems in magnetic junctions have revealed fascinating features for spintronic devices.

Tungsten disulfide (WS₂), a typical transition metal dichalcogenide (TMDC) material, transits from an indirect to direct bandgap when the thickness is thinned to a monolayer, thereby allowing for applications in transistors, photodetectors, and electroluminescent devices.

We report a facile interfacial engineering method that can drastically modulate the photoelectrochemical properties of two-dimensional transition metal dichalcogenide (TMD) semiconductors.
