Paper Abstract

Functional assemblies of materials can be realized by tuning the work function and band gap of existing materials. Here we demonstrate the structural assembly of two- and three-dimensional (2-D) and (3-D) nanomaterials and investigate the optical and electronic properties of an assembly of monolayer WS 2 on a rough polycrystalline NiO surface. Monolayer WS 2 (2-D material) was transferred onto the NiO surface using a polymer-assisted transfer technique and resulted in a surface roughness about 30 × greater than that of WS 2 on SiO 2 . Raman maps of WS 2 transferred onto NiO display a spatial nonuniformity of the E 2 g 1 ( 352    cm 1 ) and A 1 g (
