Abstract

Two-dimensional materials, specifically transition metal dichalcogenides, for highly sensitive gas sensing are emerging as effective detection technology. Platinum ditelluride (PtTe2) is an intriguing material in the realm of field-effect transistors (FETs) due to its unique electronic properties. In this study, the CVDsynthesized PtTe2 was functionalized with Au-Pd thin film for analyte-specific (H2S) sensing for better toxic gas sensitivity and selectivity. It was concluded that PtTe2, in combination with appropriate metal or oxide decorations, had great potential for ultrasensitive and selective, real-time gas sensor applications.
