Abstract

The invention discloses a preparation method of a metal-assisted two-dimensional material nanobelt. The preparation method involves preparation materials including an insulating substrate, a substratesurrounding frame, a two-dimensional nano material and a photoresist. The preparation method comprises the following specific steps that 1, the substrate surrounding frame is selected according to the required specification and shape, then the substrate surrounding frame is placed on the upper surface of the insulating substrate, and finally the two-dimensional nano material is placed on the inner side of the substrate surrounding frame until the two-dimensional nano material completely covers the insulating substrate on the inner side of the substrate surrounding frame; 2, metal is placed ina liquid for dissolving metal and then stirred; when the specification and the shape are customized on the transferred nano material, and surrounding frames of different specifications and in different shapes are prefabricated so that it can be ensured that the prepared nanobelt meets the specification and shape requirements, and deviations are avoided.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional nanometer materials, and in particular relates to a method for preparing a metal-assisted two-dimensional material nanobelt. Background technique [0002] Two-dimensional materials refer to materials that electrons can only move freely (planar motion) on the non-nano scale (1-100nm) in two dimensions, such as nano-films, superlattices, and quantum wells. The scales in one, two or three dimensions reach the nanoscale. Nanomaterials can be divided into zero-dimensional materials, one-dimensional materials, two-dimensional materials, and three-dimensional materials. Zero-dimensional materials refer to materials in which electrons cannot move freely, such as quantum dots, nanoparticles and powders. [0003] When the existing two-dimensional material nanobelts are prepared with different specifications and shapes, it is often necessary to use focused ion beams for slicing. This processing met...
