The rich family of transition metal dichalcogenides (TMDs) & transition metal trichalcogenides (TMTC) exhibits many interesting physical properties such as the metal/insulator transition, semiconducting and semimetallic transport properties, magnetism, charge-density wave state and superconductivity. Most of these properties arise from the strongly 2D character associated with the layered crystal structure. Recently, enormous interest in layered TMDs arose, e.g. WTe₂ and MoTe₂, for their topological quantum properties and in TMTC e.g. Cr₂Ge₂Te₆ because of the presence of ferromagnetism down to monolayer limit. In this talk, I will discuss first, about the synthesis and physical properties of TMDs, e.g. WTe₂, MoTe₂ and tunability of their physical properties. Second, I will discuss about the synthesis and magnetic properties of TMTC such as Cr₂Ge₂Te₆. During my talk, I will describe more in detail, why there is a renewed interest in the condensed matter physics community in understanding these low dimensional materials.
