Abstract

The invention discloses a device and a method capable of precisely controlling and transmitting a nanowire, and relates to the technical field of micro and nano-fabrication. The device comprises a femtosecond pulse light source, a microscope objective, a silver film-coated first glass sheet, a second glass sheet and an alternating-current power supply. The method comprises the following steps: firstly, focusing femtosecond pulse laser emitted by the femtosecond pulse light source by the microscope objective and then irradiating on the silver film to form a silver film gap; secondly, connectingthe alternating-current power supply with the two ends of the silver film gap, dropping a nanowire solution on the silver film gap to orientally arrange the nanowires at the two ends of the silver film gap, and reversing the first glass sheet; and thirdly, focusing the emitted femtosecond pulse laser by the microscope objective and then irradiating on one side, without being coated with the nanowire, of the first glass sheet to transfer the nanowire from the first glass sheet to the second glass sheet. Through the combination of a dielectrophoresis technology and a laser induced forward transfer technology taking graphene oxide as a dynamic release layer, precise control and nanowire transmission can be realized simply, conveniently and rapidly.

Description

technical field [0001] The invention relates to the technical field of micro-nano manufacturing, in particular to a device and method for precisely manipulating and delivering nanowires. Background technique [0002] Today, electronic products are developing rapidly in the direction of multi-function, high density, high reliability and green packaging, especially in the direction of miniaturization (even nanometer size); at the same time, the performance requirements of connectors are becoming more and more stringent, requiring nanometer connection manufacturing The number of structural parts or components has increased rapidly. With the rapid development of nanotechnology, many different kinds of nanowires are used as basic components to manufacture various nanodevices. At present, metal nanowires such as gold nanowires, silver nanowires, and copper nanowires, and semiconductor nanowires such as metal oxide nanowires have been widely studied and used to manufacture various...
