Bilayer Graphene Film on SiO2/Si Substrate (10 mm x 10 mm)

  • $ 16500


Bilayer Graphene Film on SiO₂/Si Substrate 10 mm x 10 mm (non AB Bernal stacking)

The bilayer graphene film product consists of two CVD layers produced by multiple transfer on a SiO2/Si substrate. Lower sheet resistance values can be obtained when compared to monolayer samples.

QUALITY CONTROL

All our samples are subjected to a rigorous QC in order to ensure a high quality and reproducibility of the graphene. Each batch must pass the following tests:

  • Raman Spectroscopy: I(G)/I(2D)<0.7; I(D)/I(G)<0.05
  • Optical Microscopy inspection of each individual sample to ensure good transfer quality and purity

APPLICATIONS

Graphene research, Graphene transistors and electronic applications, Graphene optoelectronics, plasmonics and nanophotonics, Graphene photodetectors (measure photon flux or optical power), Biosensors and bioelectronics, Aerospace industry (electronics, thermal interface materials, etc.), MEMS and NEMS
