Quaternary AuPdNaS <sub>2</sub> Nanoribbon for a Photodetector with High Photoresponsivity at a Wavelength of 660 nm
Two-dimensional noble transition metal chalcogenides (NTMCs) are of potential use for creating high-performance electronic and optoelectronic devices. However, the direct growth of high-quality multicomponent NTMC materials remains a significant challenge. Herein, we report the successful fabrication of quaternary AuPdNaS<sub>2</sub> nanoribbons on a Au foil substrate by an ambient-pressure chemical vapor deposition approach. The vibrational properties and carrier dynamics of AuPdNaS<sub>2</sub> nanoribbons are experimentally elucidated using temperature-dependent Raman spectroscopy and ultrafast optical pump-probe spectroscopy. In addition, the AuPdNaS<sub>2</sub> photodetector exhibits a high photoresponsivity of 235.5 A/W and a good detectivity of 1.21 × 10<sup>12</sup> Jones under 660 nm laser illumination. This work demonstrates the synthesis of quaternary AuPdNaS<sub>2</sub> and paves the way for multicomponent NTMC materials in optoelectronic applications.
