Abstract
Silver telluride, Ag2Te, has been selectively synthesized by conventional chemical vapor deposition (CVD) via the vapor-liquid-solid growth mechanism. The pre-deposited Ag film on the SiO2/Si substrate was chemically reacted with vaporized Te atoms and transformed into liquid-phase Ag-Te during the CVD process. The appropriate supply of Te vapor to the Ag film influenced the stoichiometry of Ag-Te compounds, and the formation of stoichiometric Ag-Te compounds was well-explained by the phase diagram of the Ag-Te system. We found that Ag2Te was grown in the liquid of Ag-Te under the Te-poor condition, while Ag5Te3 and Te were simultaneously solidified under the Te-rich condition. The high-temperature synthesis of Ag2Te showed higher crystallinity and better stoichiometry than the low-temperature synthesis. This study demonstrates that Ag2Te can be selectively synthesized by conventional CVD via delicate control over the phases of the complex Ag-Te system. © 2024 Author(s).
