Work Function Modulation of Molybdenum Disulfide Nanosheets by Introducing Systematic Lattice Strain.

ABSTRACT: Tuning the surface electronic properties of 2D transition metal dichalcogenides such as Molebdenum disulfide (MoS₂) nanosheets is worth exploring for their potential applications in strain sensitive flexible electronic devices. Here in, the correlation between tensile strain developed in MoS₂ nanosheets during swift heavy ion irradiation and corresponding modifications in their surface electronic properties is investigated. With prior structural characterization by transmission electron microscopy, chemically exfoliated MoS₂ nanosheets were exposed to 100 MeV Ag ion irradiation at varying fluence for creation of controlled defects. The presence of defect induced systematic tensile strain was verified by Raman spectroscopy and X-ray Diffraction analysis. The
