Abstract

The invention relates to micro-grid of a transmission electron microscope, which is of a disc-shaped carbon nano tube structure. The disc-shaped carbon nano tube structure comprises a body and a plurality of electronic transmission parts, wherein the electronic transmission parts are distributed on the surface of the body; and the density of the electronic transmission parts is lower than that ofthe body.

Description

technical field [0001] The invention relates to a transmission electron microscope microgrid, in particular to a transmission electron microscope microgrid based on carbon nanotubes. Background technique [0002] In transmission electron microscopy, porous carbon support membranes (microgrids) are important tools for carrying powder samples for high-resolution transmission electron microscopy (HRTEM) observation. With the continuous development of research on nanomaterials, the application of microgates in the field of electron microscopy characterization of nanomaterials has become increasingly widespread. In the prior art, the microgrid applied to the transmission electron microscope is usually made by covering a metal grid such as a copper grid or a nickel grid with a porous organic film, and then vapor-depositing a layer of amorphous carbon film. However, when the above-mentioned microgrid is used to analyze the composition of the high-resolution transmission electron m...
