Abstract:
Two‐dimensional MoS 2 can be used for various electronic and optoelectronic applications due to its atomically thin structure and high surface area. Keeping such applications in mind, we report, the role of different solvent in the synthesis of 2D‐MoS 2 nanosheets (NSs) via liquid‐phase exfoliation method, and these nanosheets are further studied for photodetector application. Bulk MoS 2 powder has been exfoliated in various solvents like deionized water (DI), 1,2‐dichlorobenzene (DCB), dimethylformamide (DMF), and N‐methyl‐pyrrolidone (NMP). The structural and optical properties of samples have been investigated. From the structural analysis, it has been found that MoS 2 NSs have lateral dimensions in micron and are few nanometer thick. These NSs are single plane oriented with a 2H phase, which have semiconducting nature. The optical properties of MoS 2 NSs have been studied by UV‐Visible absorption spectroscopy, and it is found that the optical band gap has been varied between 1.62 eV to 1.78 eV. The photoresponse of these synthesized NSs has been studied and found that NSs exfoliated in DMF and NMP show better photoresponse.
