Graphite atome
WebGraphite conducts electricity. It has free electrons that conduct electricity by carrying charge from one location to another. Each carbon atom in graphite has a covalent link with three other atoms, freeing one atom. The free electron moves across the graphite material and does not bond to any particular atom. WebGraphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb-shaped lattice, and the structural component of some 0D, 1D, and 3D carbon allotropes. It is just one atom thick, yet tremendously …

WebAtomic force microscopy can directly image the atomic structure of graphite. I don't see any reason you couldn't image a piece of writing, though preparing the sample to be imaged edge on would be challenging. It might be difficult to count the layers, but at the very least it would give a very accurate measurement of the thickness. http://large.stanford.edu/courses/2024/ph240/friedman2/
