Suspended Graphene on TEM Grids (Quantifoil Gold) – Pack 4 units

Suspended Monolayer Graphene on TEM Grids (Quantifoil) – Pack 4 units – Processed in Clean Room Class 1000. The monolayer graphene is grown by CVD and transferred onto a Quantifoil TEM grid. The graphene is suspended over 2μm holes. Available in either in suspended monolayer graphene on TEM or suspended bilayer graphene on TEM. Sold as packs of 4.

Tips for selecting which layer type (monolayer vs. bilayer) – Your application should guide which one you choose. The monolayer can be used for characterization or to deposit other molecules and analyze them. In the bilayer the covered grid holes are higher (higher yield) and its mecanic resistance is also higher.

Quality control

All samples are subjected to a rigorous QC in order to ensure a high quality and reproducibility of the graphene. All CVD materials are processed in Clean Room Class 1000. Each batch must pass the following tests:

  • Raman Spectroscopy on each batch:
  • I(G)/I(2D)<1
  • I(D)/I(G)<0.1
  • FWHM (G) < 23cm-1
  • FWHM (2D)< 44cm-1
  • Optical Microscopy inspection of each individual sample to ensure good transfer quality and purity

    If your application requires more specific controls (AFM, SEM...) please do not hesitate to contact us.
