By transferring graphene to a flat grid with small circular holes in it we created new samples with flatter, less wrinkled graphene that make performing eV-TEM easurements on graphene easier and increase their quality. We improved the alignment of the imaging system of the microscope and determined the resolution of eV-TEM using the new samples to image graphene. We found a method to deposit 10nm gold nanoparticles on graphene suitable for eV-TEM measurements and a method to deposit ferritin on graphene that we should be able to image as well. We conclude that the spatial resolution of the current set-up of eV-TEM is 10nm and that it is possible to image gold nanoparticles deposited on graphene with eV-TEM.Show less
