The nonlocal response associated with the collective oscillation of conduction electrons (plasmons) in atomically thin films plays a significant role in the optical response. Here we exploit the use of surface plasmons to characterize the nonlinear optical behavior of few atom-thick films. The results show beneficial use of thinner films that are computed employing a full quantum mechanical model that incorporates details of the crystallographic orientation allowing us to exploit the facets (111) and (100) in the random phase approximation. These results facilitate the fabrication of nanophotonic devices based on crystalline metals films which offer lower losses than their amorphous counterparts.
