What microscope is used for graphene research
Of course, it is an atomic force microscope (AFM). Looking at the height map, a single layer of graphene is less than 1 nm. It should be said that AFM is the most convenient means to characterize graphene materials. Of course, care should be taken to distinguish dust, salts, and graphene molecules during AFM characterization.
Of course, optical microscopy and scanning electron microscopy (SEM) can also be used to characterize graphene. There is also a high-resolution transmission electron microscope HRTEM that can see the honeycomb atomic image of graphene, and can see the defects of graphene oxide after reduction.
Nowadays, the quality of books compiled by many scholars is getting worse and worse, but "Graphene-Structure, Preparation Method and Performance Characterization" edited by scholars from Tsinghua University is still reasonable. There are some mistakes in the book, which do not affect the reference. Compared with some books It is much better to compile a large number of documents without logical rules to show how many documents you have read.
