We review recent research progress on mass production of twodimensional (2D) materials beyond graphene, including “top-down” exfoliation and “bottom-up” synthetic approaches. In addition, the applications that require massively-produced 2D materials are discussed.

Here we review the recent in situ transmission electron microscopy (TEM) works on the formation of two-dimensional (2D) crystals under electron irradiation, thermal excitation as well as voltage bias. The underlying mechanisms are also elucidated in detail, providing key insights into the nucleation and formation of 2D crystals.

A convenient experimental method for growing centimeter-scale PtSe2, PtTe2 films and the hitherto-unreported PtTe film via deposition of Pt film followed by selenization or tellurization is reported. A phase control between the new PtTe phase and PtTe2 phase is also achieved by annealing under Te flux.

Substitutional doping in two-dimensional (2D) group 6 transition metal dichalcogenides (MX2, M = Mo, W; X = S, Se, Te) is key to enabling novel functionalities of these materials. We review the recent progress in the understanding of the physical effects of doping.

Surface charge transfer doping (SCTD) is emerging as an effective and non-destructive doping technique to provide reliable doping capability for two-dimensional (2D) materials as well as to tune their electronic and optical properties, which facilitates the rational design and construction of 2D-based functional devices with the optimized performance.
