Abstract: The exemplary embodiments describe techniques for a controlled chemical vapor deposition growth and transfer of arrayed TMD monolayers on predetermined locations, which enable the formation of single crystalline TMD monolayer arrays on specific locations. The unique growth process includes the patterning of transition metal oxide (e.g., MoO3) on the source substrate contacting the growth substrate face-to-face, where the growth of single crystalline TMD monolayers with controlled size and location, exclusively on predetermined locations on the growth substrates is accomplished. These TMD arrays can be align-transferred using a unique process that combines the wet and stamping transfer processes onto any target substrate with a pin-point accuracy, which dramatically enhances the integrity of transferred TMDs.
