Abstract

The invention discloses a two-dimensional material probe for an atomic force microscope, a preparation method and an application thereof. Wherein, the two-dimensional material probe includes: a cantilever beam, a hard ball and a two-dimensional material layer, the upper part of the hard ball is fixedly connected with the tip of the cantilever beam; the two-dimensional material layer is adhered to The bottom of the hard pellet. The two-dimensional material probe has a simple and stable structure, fast preparation speed and low cost, and is very suitable for friction experiments related to a specific two-dimensional material.

Description

technical field [0001] The invention belongs to the field of atomic force microscopy, and in particular relates to a two-dimensional material probe for atomic force microscopy, a preparation method and application thereof. Background technique [0002] Friction and wear are the two main obstacles to improving the efficiency of mechanical systems, which will lead to a large amount of unnecessary energy dissipation and damage to parts and components. Therefore, in the design of high-performance micro-electromechanical systems or nano-electromechanical systems, it is required near zero friction and extremely low wear. Super-slip refers to the lubrication state when the friction coefficient drops to 0.001 or even lower, and it is an effective method to achieve near-zero friction. Due to the weak interlayer van der Waals interaction of graphene and other two-dimensional layered materials, they can achieve superslip under certain conditions, and their superslip properties have be...

Problems solved by technology

However, the preparation process of these two types of methods is complicated and the cost is high.

The third method is to directly adsorb graphene on the tip of the atomic force microscope through friction transfer technology, but this method is more accidental, and the graphene is easy to fall off during the movement of the tip, and the stability is poor, so it is difficult to use in related friction experiments
