Investigating the electrical transport mechanisms in two-dimensional transition metal trichalcogenides (TMTCs) is crucial for advancing next-generation electronic devices. ZrTe3, a van der Waals 2D material, features quasi-1D atomic chains with tunable inter-chain distances achieved through chemical doping (e.g., Se, Hf, Cu, Ni). This tuning affects electron-phonon coupling and the emergence of mixed valence states, which, in turn, influence conductivity and the onset temperatures of charge density waves (CDW) and superconductivity (SC). A possible mechanism for the initiation of CDW and SC phenomena will be presented.
