Numerical simulations of the changes in s-polarised (a) and p-polarised (b) reflectance at gating voltages, Vg using the interference effect and electrical tunability of the refractive index of monolayer MoS2. Inset: experimental and modelled s-polarised reflectance of the Au/Si3N4/MoS2 hybrid waveguide nanostructure at Vg = 0
