Two-dimensional transition metal dichalcogenides (TMDs) like WS2 and WSe2 demonstrate strong light-matter interactions, including exciton formation, pronounced photoluminescence, and enhanced second-harmonic generation. Van der Waals epitaxy allows for the growth of these semiconducting monolayers on…
Monolayer transition metal dichalcogenides, such as tungsten diselenide, have recently attracted considerable attention due to their reduced dielectric screening and direct bandgap, which result in high exciton binding energy and strong photoluminescence. The integration of monolayer transition metal…

A characteristic property of monolayered transition metal dichalcogenides is their strong nonlinear response. While they display a high conversion efficiency per atomic layer, due to their low thickness, the absolute value of their nonlinear response remains low. Here enhancement of the second harmonic…
A simple, large area, and cost‐effective soft lithographic method is presented for the patterned growth of high‐quality 2D transition metal dichalcogenides (TMDs). Initially, a liquid precursor (Na 2 MoO 4 in an aqueous solution) is patterned on the growth substrate using the micromolding in capillaries…
We report for the first time the direct growth of molybdenum disulfide (MoS 2 ) monolayers on nanostructured silicon-on-insulator waveguides. Our results indicate the possibility of utilizing the Chemical Vapour Deposition (CVD) on nanostructured photonic devices in a scalable process. Direct growth…
