ACS Material CVD Grapehen on Silicon Nitride TEM Grids are made by Trivial Transfer Graphene.
1. Four thicknesses of CVD graphene:
Available in either 1, 2, 3-5 or 6-8 layers
2. TEM Substrate:
200µm thick 3.0mm hexagonal silicon substrate with a 0.5x0.5mm aperture and 200nm thick silicon nitride membrane with approximately 6,400 2µm holes
3. Graphene coverage of the TEM grid is > 75%. (The graphene coverage is typically >75% of the whole 3.05mm diameter silicon TEM grid which encompasses the holey silicon nitride membrane.)
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.
|Type||Thickness of Graphene||Transparency of Graphene||TEM Grid/AFM Substrate||Support Film|
|1 Layer||~0.35nm||~96.4%||2μm Hole Silicon Nitride||Silicon Nitride|
|2 Layers||~0.7nm||~92.7%||2μm Hole Silicon Nitride||Silicon Nitride|
|3-5 Layers||1.0-1.7nm||~85.8-90.4%||2μm Hole Silicon Nitride||Silicon Nitride|
|6-8 Layers||2.1-2.8nm||~78.5-83.2%||2μm Hole Silicon Nitride||Silicon Nitride|
