Graphene on Ultra-flat Thermal SiO2 Substrate
5x5mm
Product Detail
CAS No.: 7782-42-5
Among our outstanding lineup of graphene products is graphene on ultra-flat thermal SiO2 substrate. These products were designed specifically for AFM studies but are versatile enough for use in many other applications. They come in packages of 5, 10, or 25 to a box.
Each 5mm x 5mm ultra-flat thermal SiO2 substrate includes a 200nm SiO2 film grown on a 675 µm ultra-flat silicon wafer. The technicians at ACS Material use our proprietary trivial transfer method to transfer CVD graphene to the SiO2 substrate. You can choose from four thicknesses of graphene: single layer, double layer, 3-5 layers, or 6-8 layers. The graphene coverage on each silicon oxide substrate is greater than 75%.
ACS Graphene on Ultra-Flat SiO2 Substrate is made by Trivial Transfer Graphene.
Characteristics
