METHODS AND APPARATUSES FOR POSITIONING NANO OBJECTS WITH ASPECT RATIOS

The present invention is notably directed to apparatuses and methods for positioning nano objects (20) on a surface. The method comprises: providing (S10 S50) two surfaces (15 17) including a first surface (15) and a second surface (17) in vis à vis wherein at least one of the two surfaces exhibits...

Summary:The present invention is notably directed to apparatuses and methods for positioning nano objects (20) on a surface. The method comprises: providing (S10 S50) two surfaces (15 17) including a first surface (15) and a second surface (17) in vis à vis wherein at least one of the two surfaces exhibits one or more positioning structures (16 16a) having dimensions on the nanoscale; and a ionic liquid suspension (30) of the nano objects between the two surfaces wherein each of the surfaces forms an electrical double layer with the ionic liquid suspension each of the two surfaces having a same electrical charge sign; and letting (S60) nano objects in the suspension position according to a potential energy (31) resulting from the electrical charge of the two surfaces and depositing (S70) one or more of the nano objects on the first surface according to the positioning structures by shifting minima (32) of the potential energy towards the first surface.
