METHODS AND APPARATUSES FOR POSITIONING NANO-OBJECTS WITH ASPECT RATIOS |
摘要 |
<p>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.</p> |
