Jedno-/lub dwuwarstwowy wafel grafenowy 285nm SiO2

Single/Double Layer

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


  • Test sample for Raman spectroscopy
  • Great for educational purposes
