Chemical Vapor Deposition of Phase-Pure 2D 1T-CrS2

2D transition-metal dichalcogenides of chromium are technologically important due to their diverse electrical and magnetic properties. Herein this study, 1T-CrS2 nanosheets as thin as 2 nm are successfully synthesized by an atmospheric pressure space-confined chemical vapor deposition method. The prepared CrS2 nanosheets are stable at room temperature. Electrical measurement shows a quasi n-type semiconductor behavior. In addition, terahertz characterizations on 1T-CrS2 reveal its potential to integrate with the ultrathin infrared sensor platforms.
