Monolayer graphene film is grown by CVD processing onto copper foil, then transferred onto quartz
Properties of Graphene Film on Quartz:
The thickness and quality of graphene films is controlled by Raman Spectroscopy
The graphene coverage of this product is about 95%
The graphene film is continuous, with occasional holes and cracks
The graphene film is polycrystalline, i.e. it consists of grains with different crystallographic orientation
The transmission of our graphene film is above 97%
Sheet Resistance: 660-1,500 Ω/square
Raman Spectrum of Graphene on Quartz
Properties of Quartz Substrate:
We use G.E. 124 Fused Quartz Substrates
Knoop Hardness: >600 Kg/mm2
Density: 2.21 g/cm3
Transparent conductive coatings (TCO)
ITO replacement (touch-screen applications)
We can provide you with blank substrates without graphene for a small fee. If you require this, please contact us before you place your order.
We can manufacture custom, large-size windows, and use different shapes of quartz slides. You may also send us your own substrates for coating. Few-layer graphene coatings with a lower sheet resistance and lower transparency can also be prepared. Please contact us for a quote.
Our graphene films are made by a PMMA assisted transfer method. Please refer to the references below for more details.
