Electric-field-assisted placement of nanomaterial from solutions with patterned graphene. Artistic rendering of electric-field-assisted placement of nanoscale materials between pairs of opposing graphene electrodes structured into a large graphene layer located on top of a solid substrate. The sketches on the left-hand side visualize the key steps of the method: structuring a large-scale graphene layer to form local electrodes, applying a AC voltage for facilitating the field-assisted placement of nanomaterials from solution (shown are carbon nanotubes), and removing the graphene structure once the placement is complete. In the visualization on the right-hand side, quantum dots (0D), single-walled carbon nanotubes (1D), and layers of molybdenum disulfide (2D) are shown as representative nanomaterials that can be assembled at large scale based on the graphene-based, electric-field-assisted placement method
