Multilayer Graphene on 285 nm Silicon Dioxide Wafer: 10 pack

Multilayer Graphene on 285 nm Silicon Dioxide Wafer: 10 pack

 

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/square

 

Optical Image of Multilayer Graphene on SiO2


Multilayer Graphene on Silicon-Dioxide

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.
