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