Multilayer Graphene on 285 nm Silicon Dioxide Wafer: Packs



Multilayer 5 Pack

Multilayer Graphene on 285 nm Silicon Dioxide Wafer: 5 pack
Ordering Code:  MULTI-SIO2-5P

A 5 pack of multilayer CVD-grown graphene transferred onto 1cm x 1cm silicon wafers (p-doped) with a 285 nanometer silicon dioxide coating.

Properties of Graphene Film:

  • The thickness and quality of our 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
  • Sheet Resistance: 660-1,500 Ω/□



Multilayer 10 Pack

Multilayer Graphene on 285 nm Silicon Dioxide Wafer: 10 pack
Ordering code:  MULTI-SIO2-10P

A 10 pack of multilayer graphene on 1cm x 1cm silicon wafers (p-doped), with a 285 nanometer silicon dioxide coating.

Properties of Graphene Film:

  • The thickness and quality of our 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
  • Sheet Resistance: 500-1,500 Ω/□

Optical Image of Multilayer Graphene on SiO2

The graphene grown on nickel film is multilayer and is not uniform. It looks like a patchwork whereas the “patches” have different thicknesses. The thickness of the film varies from 1 to 7 layers, with an average of 4. The graphene layers within the same patch are aligned relative to each other (there is a graphitic AB-staking order). The size of the patches is about 3-10 microns.

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:

  • Graphene electronics and transistors
  • Conductive coatings
  • Aerospace industry applications
  • Support for metallic catalysts
  • Microactuators
  • MEMS and NEMS
  • Chemical and biosensors
  • Multifunctional materials based on graphene
  • Graphene Research

Our graphene films are manufactured using a PMMA assisted transfer method. Please refer to the references below for more details.
