Abstract
A method for positioning nano-objects on a surface and an apparatus for implementing the method. The method includes: providing a first surface and a second surface in a position facing each other, where one or more of the surfaces exhibits one or more position structures having dimensions on the nanoscale; providing an ionic liquid suspension of the nano-objects between the two surfaces, where the suspension comprises two electrical double layers each formed at an interface with a respective one of the two surfaces, and the surfaces have electrical charges of the same sign; enabling the nano-objects in the suspension to position according to a potential energy resulting from the electrical charge of the two surfaces; and depositing one or more of the nano-objects on the first surface according to the positioning structures by shifting the minima of the potential energy towards the first surface.
