Frequently Asked Questions
A: Our standard product is a Quantifoil TEM grid of Au. The holes are 2microns and the total thickness is about 12 microns.
A: Yes. The customer can provide us with their own grids with the desired hole size. The maximum size that we can cover with good coverage is up to 7microns. We can transfer up to 40microns but the coating percentage decreases.
A: The standard film contains around 10 at.% of residues. An annealing treatment can be performed in order to achieve a cleaner graphene film.
