Nano cutting knife for processing nano material and use method thereof

Abstract

The invention discloses a nano cutting knife for processing nano material and a use method thereof, the cutting knife comprises a shell having U-shaped cross section, a circuit general control arranged at the opening end of the U-shaped shell, a piezoelectric ceramic drive barrel arranged at one end in the shell, a metal copper cap and a metal probe mounted in the metal copper cap, a four-electrode connection wire arranged at the other end in the shell, a first support ceramic blade, a spring compression module, a second support ceramic blade, a four-electrode connection blade and a carbon nano tube, the metal copper cap and the metal probe are controlled by the piezoelectric ceramic drive barrel for having precision movement, the carbon nano tube is fixed on any two electrodes of the four-electrode connection blade; the general control circuit module is used for offering the load voltage for two ends of the carbon nano tube, the carbon nano tube generates the joule heat, the metal copper cap and the metal probe are controlled by the piezoelectric ceramic drive barrel for moving, the nano wire to be processed is located on the carbon nano tube for having the nano cutting operation.

Description

technical field [0001] The invention relates to the field of nano devices used for micro-nano processing of nano materials, in particular to the design of a nanotube cutting knife used for cutting and processing nano materials. Background technique [0002] With the development of micro-nano electronics, the size of electronic devices is getting smaller and more integrated, and the traditional micro-electro-mechanical systems are gradually developing into nano-electro-mechanical systems. The construction of micro-nano devices requires the use of various nanomaterials, including one-dimensional nanowires, nanoparticles, two-dimensional nanosheets, and so on. There are usually top-down microfabrication techniques and bottom-up self-assembly methods for preparing nanomaterials, both of which have their own characteristics. However, since top-down microfabrication processes are usually suitable for fabricating structures on substrates, it is difficult to obtain suspended, freel...
