Multilayer h-BN (Boron Nitride) Film grown on Copper Foil: 2" x 1"

Graphene SupermarketSKU: CVD-2X1-BN-ML

Sale price$275.00


Multilayer h-BN (Boron Nitride) film grown in copper foil. 

h-BN is an insulator with a direct band gap of 5.97 eV. Due to its strong covalent sp2 bonds in the plane, the in-plane mechanical strength and thermal conductivity of h-BN has been reported to be close to that of graphene. h-BN has an even higher chemical stability than graphene; it can be stable in air up to 1000 °C (in contrast, for graphene the corresponding temperature is 600 °C).

During Chemical Vapor Deposition, BN is grown on both sides of the copper foil


Close to complete coverage (90-95%), with some minor holes

Average Thickness of BN film is 13 nm

Thickness of the copper foil is 20 microns

Quality is confirmed by TEM. TEM shows perfect hexagonal structure.

If transferred onto an SiO2 substrate, the BN film may be seen as a white film. However, it is difficult to recognize the BN film on copper using a microscope.

Transfer: PMMA Procedure, similar to that of graphene. It may be transferred on most substrates, which we may do in-house as custom work.
