Abstract

The invention discloses a method for arranging a one-dimensional nanowire array in a large area from a solvent, which is a method with simplicity and easiness in operation. The method comprises the following steps of: firstly taking oriented spinning nano fiber on a roller as a template, immersing the roller with the oriented fiber into a nanowire suspension, rotating the roller in the nanowire suspension at a certain speed, causing the nanowires in the solution to be adsorbed into the roller with the oriented fiber, finally putting the roller with oriented-adsorbed nanowires on a designed device, adding a little water or organic solvent lubricant on a substrate, and driving the roller with the oriented spinning fiber to roll forward by a transmission device to realize a successful transfer of the nanowires adsorbed on the fiber to the substrate. The method disclosed by the invention not only has convenience for operation, and the needed equipment is easy to design and manufacture; the method is applicable to various types of substrates, easy to realize large-area parallel arrangement of nanowires, and available for preparation of micron/nanometer electronic detecting members and the like.

Description

technical field [0001] The invention relates to a method and a device for assembling a one-dimensional nanowire array from a solution in a large area, and belongs to the intersection field of micro-nano device manufacturing and microelectronic technology. Background technique [0002] At present, the assembly of one-dimensional nanowires is attracting widespread attention, because assembling these one-dimensional nanowires is a necessary step for nanowire deviceization, and it is also the only way for nanowires to enter practical production applications. Nanowires can be used as optoelectronic detection devices, field effect tubes, sensor detectors, etc. after deviceization. Therefore, in recent years, researchers have invented many methods for assembling one-dimensional nanowires, including LB film method, microfluidic method, electric field-assisted assembly method, selective chemical or biological patterning method, magnetic field Auxiliary method, light trapping method,...
