General description

Molybdenum disulfide is a two dimensional layered material. Monolayers of transition metal dichalcogenides (TMDs)exhibit photoconductivity. The layers of the TMD can be mechanically or chemicaly exfoliated to form nanosheets. TMD such as MoS2 shows non linear optical property, it was studied in detail by ns pulsed laser at 1064 nm and 532 nm.

Mechanical alloying is a “brute force” method of affecting alloying and chemical reactions. The mixture of reactant powders and several balls are placed in the milling jar of a high-energy ball mill, for example, a shaker mill or a planetary mill.
