We present the direct chemical vapor deposition (CVD) growth of monolayer molybdenum disulfide (MoS2 ) onto periodically poled lithium niobate. Single-layer MoS2 displays a preference for the ferroelectric domains polarized “up” with respect to the surface. This may offer the possibilities of templated growth of TMD films using the substrate ferroelectric polarization as a pattern. Piezoresponse force microscopy reveals that the MoS2 film maintains the substrate polarization on the “up” domains while partially quenching it on the “down” domains. Electrical transport measurements suggest the ability to invert the single-layer CVD MoS2 majority charge carrier via gating depending on the domain orientation of the periodically poled lithium niobate substrate.
