Abstract
Potential applications of monolayer of transition metal dichalcogenides (TMDs) in optoelectronic and flexible devices are under heavy investigation. Although TMD monolayers are highly robust to external mechanical fields, their electronic structure is sensitive to compressive and tensile strain. In addition, intrinsic point defects are present in synthesized samples of these 2D materials which leads to the modification of their electronic and optical properties. Presence of vacancy complexes leads to absorption with larger dipole matrix elements in comparison with the case of simple transition metal vacancies. Using first principles calculations, the effect of various strain situations on the absorption spectra of such defective monolayers is scrutinized and also shows that strain engineering allows for reversible tuning of the optical properties.
