Abstract

The invention discloses a preparation method of an addressable nano molecular junction, belonging to the field of micro machining of nano materials and testing of nano electronic devices. The preparation method comprises the steps of: firstly, washing a piezoelectric ceramic substrate; preparing an insulation layer film on the piezoelectric ceramic substrate and obtaining a micro nano strip-shaped bulge on the middle; preparing a narrow-neck-shaped Au electrode film layer on the insulation layer film; placing the piezoelectric ceramic substrate in a vacuum chamber, respectively welding leads on two sides of the piezoelectric ceramic substrate and leading out a vacuum chamber; electrifying the piezoelectric ceramic substrate to ensure that the Au electrode film layer is broken to obtain a metal electrode pair with a nano gap; and finally, filling an organic molecular material in the nano electrode gap to obtain the addressable nano molecular junction. According to the invention, the gap controllable nano Au electrode pair is obtained through regulating bias voltages and electrifying time of two ends of the piezoelectric ceramic substrate, thus pollution and thermally induced ablation on a metal molecular interface when electrodes deposit on a molecular layer are avoided through molecule self-assembly in the gap.
