Product Detail

CAS No.: 7782-42-5
ACS Graphene on Ultra-Flat SiO2 Substrate is made by Trivial Transfer Graphene.
1. Four thicknesses of CVD graphene:
Available in either 1, 2, 3-5 or 6-8 layers
2. Substrate: 
The Ultra-flat Thermal SiO2 Substrate consists of a 200nm thermally grown SiO2 film on an ultra-flat silicon wafer with a normal thickness of 675 µm. The size is 5mm x 5mm.
3. Graphene coverage of the ultra-flat silicon is > 75%
