Graphene & Graphene Oxide Support Films for TEM
n Graphene on Ultra-Flat Thermal SiO2 Substrate Characteristics
1. Four thicknesses of CVD graphene Available in either 1, 2, 3-5 or 6-8 layers
2. TEM Substrate The Ultra-flat Thermal SiO2 Substrate consists of a 200 nm thermally grown SiO2 film on an ultra-flat silicon wafer with a normal thickness of 675 µm. The size is 5 mm x 5 mm.
3. Graphene coverage of the TEM grid is better than 75% Appearance
The graphene film appears as a near-transparent to light-grey film on the surface of the red-brown microporous copper TEM grid. For support, the TEM grid is attached using epoxy to a gold-colored beryllium-copper disk with a 2 x 1 mm aperture.
