Abstract

Authors report the synthesis of PdSe_2- _xS_x solid-solutions (0 ≤ x ≤ 0.86) with pentagonal layered structure and their transport properties. From structural and optical characterizations, it can be confirmed that S atoms are successfully substituted on Se-site in the parent phase of PdSe₂. By analyzing the electrical and thermal transport characteristics, it reveals that the density of states effective mass as well as band gap of PdSe_2- _xS_x can be controlled by varying x. It strongly suggests that S substitution can be an effective compositional tuning approach for engineering the electronic band structure in pentagonal layered PdSe₂ system.
