WEBAug 1, 2014 — The commercial and synthesised few-layer graphene oxide, prepared using oxidation reactions, and few-layer reduced graphene oxide samples were structurally and chemically investigated by the X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron spectroscopy methods, i.e. X …
Graphene Oxide: Structural Analysis and Application as a Highly ...
WEBAug 18, 2009 — We report on the structural analysis of graphene oxide (GO) by transmission electron microscopy (TEM). Electron diffraction shows that on average the underlying carbon lattice maintains the order and lattice-spacings of graphene; a structure that is clearly resolved in 80 kV aberration-corrected atomic resolution TEM images.

WEBDec 1, 2019 — Transmission electron microscopy (TEM) is a useful tool for identifying single-layer and few-layer graphene oxide sheets [37]. TEM uses electrons that pass through the sample with contrast resulting from differences in electron density, so multiple sheets appear darker relative to single sheets [38].
