Graphene Supermarket 铜基六角氮化硼单层

Single layer 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
Specifications:
Close to complete coverage (90-95%), with some minor holes
Thickness of the copper foil is 20 microns
High crystalline quality, see SAD (Selected area [electron] diffraction) data
Quality is confirmed by TEM.
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.
