Abstract Scope |
PtSe2 is attracting attention as a novel two-dimensional material with high mobility and a bandgap suitable for near-infrared light. LIDAR (light detection and ranging) is one of the significant applications of the near-infrared light photodetector, which is indispensable for the automatic driving of automobiles. Therefore, it is necessary to develop a compact photodetector that can be used at room temperature and has a low operating voltage. In this study, PtSe2 film was prepared on Si/SiO2 substrate by CVD using DDAP (Dimethyl (N, N‑Dimethyl-3-Butene-1-Amine‑N) Platinum) precursor and Se vapor. Then, Au nanorods were spin-coated on the PtSe2 surface to enhance the photocurrent with localized surface plasmon resonance of Au nanorods. In this presentation, we discuss the relationship between the concentration of Au nanorods and photocurrent and the mechanism of photocurrent enhancement by localized surface plasmon resonance. |
