Graphene on Silicon Nitride TEM Grids 2.5 holes
Graphene on Silicon Nitride TEM Grids (2.5 µm holes) available in four thicknesses of CVD graphene which is either 1, 2, 3-5 or 6-8 layers. TEM substrate is 200 µm thick 3.0 mm hexagonal silicon substrate with a 0.5 x 0.5 mm aperture and 200 nm thick silicon nitride membrane with approximately 6,400 2.5 µm holes. Graphene coverage of the TEM grid is better than 75%.
Product Information
Appearance
Solid hexagonal disk with a greenish hue. The graphene film appears as a near-transparent to light-grey film on the surface of the microporous Silicon Nitride membrane.
