초록

Transition metal dichalcogenides (TMDs) have attracted much attention because of their excellent optical and electrical properties, which are the applications of next generation photoelectric devices. In this study, $MoS_2$, which is a representative material of TMDs, was formed by magnetic sputtering method and surface changes and optical characteristics were changed with thickness variation. In addition, by implementing the photodetector of $MoS_2/p-Si$ structure, it was confirmed that the change of the electrical properties rather than the change of the optical properties according to the thickness change of $MoS_2$ affects the photoresponse ratio of the photodetector. This result can be used to fabricate effective photoelectric devices using $MoS_2$.
