Single/Double Layer Graphene on 285 nm Silicon Dioxide Wafer: 10 Pack
Single/Double Layer Graphene on 285 nm Silicon Dioxide Wafer: 10 Pack
Ordering Code: DBL-SIO2-10
A ten pack of mono and bilayer graphene on 1cm x 1cm silicon wafers (p-doped) with a 285 nanometer silicon dioxide coating.
The samples have nearly full monolayer coverage with 10-30% coverage of bilayer graphene islands. They are a great low-cost alternative to monolayer graphene for select purposes.
Properties of Graphene Film:
- 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
Properties of Silicon/Silicon Dioxide Wafers:
- Oxide Thickness: 285 nm
- Color: Violet
- Wafer thickness: 525 micron
- Resistivity: 0.001-0.005 ohm-cm
- Type/Dopant: P/Boron
- Orientation: <100>
- Front Surface: Polished
- Back Surface: Etched
Applications:
- Test sample for Raman spectroscopy
- Great for educational purposes
