Frequently Asked Questions

A: Our standard Suspended Monolayer Graphene on TEM Grids is transferred on holes of 2microns. You can provide your own grids with your desire size and we can transfer on them. The maximum size that we can cover with good coverage is up to 7microns.

A: There is around 2-3% of hydrocarbon contamination in the surface. An annealing at 300C to clean areas can be done and to be measured with a TEM microscope.

A: The TEM grid substrate is a standard Quantifoil TEM grid Au coated. It is 500k in vacuum and X-ray Resistive.
