Graphene Oxide TEM Substrates

January 19, 2016 DannyBoy

Characteristics

Available as single and 2-layer films
Thickness as measured by EELS is ~0.8 for the single-layer to 1.5nm for the 2-layer films
The graphene oxide film covers approximately 70% of the TEM grid
10-100nm diameter pores are to be found randomly scattered about the graphene oxide film

Available on:

Lacey carbon, 300 mesh copper grids;
Holey silicon nitride substrate
Ultra-flat thermal silicon dioxide silicon substrate

2-layer graphene oxide approximately 1-1.5nm in thickness as measured by EELS
