Direct synthesis of few atomic layer MoS2 films on a plastic substrate by pulsed laser deposition technique

Using the pulsed laser deposition method high quality few atomic layers of MoS₂ continuous films were grown on glass and flexible polyimide substrates. Comparative studies of XRD, Raman scattering, photoluminescence and optical absorption spectra confirm the correlation between the strain effects and properties of the films appearing due to the large mismatch between the thermal expansion coefficients of the substrate and ultrathin MoS₂ layers.
