Transition metal dichalcogenide having a heterostructure, method for manufacturing the same, and photoelectric device including the same

Abstract

The present invention relates to a transition metal dichalcogenide having a heterostructure, a method for manufacturing the same, and a photoelectric device including the same. More specifically, the method for manufacturing a transition metal dichalcogenide having a heterostructure of the present invention can form a uniformly, evenly, and continuously grown transition metal dichalcogenide having a heterostructure through hydrophilic treatment of a substrate, pH control of a transition metal precursor solution, and mixing of sodium cholate. Furthermore, by controlling the concentration of the transition metal precursor, it is possible to manufacture hierarchical transition metal dichalcogenides, which exhibit excellent reproducibility and can be applied to photoelectric devices.
