Figure 1From: Synthesis, properties and potential applications of two-dimensional transition metal dichalcogenides There are a number of possible layered structure TMDs materials consist of 16 transition metals and three chalcogen atoms. In the case of Co, Rh, Ir and Ni, only a few layered structures are observed, for example NiS2 forms an apyrite structure, however NiTe2 forms layered structure [43].Back to article page
