Abstract

Monolayers of transition-metal dichalcogenides (TMDs) like Molybdenum Disulphide (MoS₂) are direct-bandgap semiconductors with thicknesses below 1 nm. Due to their broken inversion symmetry, such monolayers feature a second-order nonlinear susceptibility, which is enhanced in spectral regions close to excitonic resonances [1].
