Interlayer exciton mediated second harmonic generation in bilayer MoS2

Interlayer exciton mediated second harmonic generation in bilayer MoS2

Efficient second-harmonic generation (SHG) occurs for crystals with broken inversion symmetry, such as transition metal dichalcogenide monolayers. Here the authors show SHG tuning in bilayer MoS2 - an inversion-symmetric crystal - mediated by interlayer excitons.
