The stacking of few layers of transition metal dichalcogenides (TMDs) and their heterostructures allows us to create new structures, observe new physical phenomena, and envision new applications. Moreover, the twist angle in few-layer TMDs can signif

We report on second harmonic generation from MoS2/WS2 as-grown heterostructures. The two crystal structures naturally align with 0° and ^60. twist angles. While the former enhances, the latter decreases the nonlinearity from individual layers.

Monolayers of MoS 2 and WS 2 , as well as their vertical heterostructures, were synthesized via chemical vapor deposition. The samples were then characterized via microRaman and micro-photoluminescence spectroscopies, and by second harmonic generatio

We report on the optical third harmonic generation in mechanically exfoliated franckeite, a natural Van der Waals heterostructure. Results show a nonlinear signal that is anisotropic and 1300-1500 times stronger than that of monolayer graphene.
