Challenges in Liquid-Phase Exfoliation of Non-van der Waals Cr₂S₃.

ABSTRACT: Two-dimensional (2D) chromium(III) sulfide has recently attracted increased attention from researchers due to its interesting electronic and magnetic properties and has great potential for application in spintronics and optoelectronics to create sensitive photodetectors. However, the synthesis of 2D Cr2S3 crystals is still a challenging task. At present, the mainly used method is vapor deposition, which is a poorly scalable, time-consuming, and expensive process. In this study, liquid-phase exfoliation of bulk chromium sulfide in different solvents (dimethyl sulfoxide (DMSO) and N-Methyl-2-pyrrolidone (NMP)) is demonstrated. It was found that exfoliation using an ultrasonic device with a titanium probe in both solvents produced Cr2S3 nanosheets with lateral dimensions ranging from 40 to 20
