提供高質量的銅基單層六角氮化硼薄膜與銅基多層六角氮化硼薄膜,六角氮化硼結構是類石墨烯結構,具有很高的研究價值,也可以用轉移石墨烯的方法轉移六角氮化硼材料。表征完備,質量可靠。

 

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.

 

 

  • TEM shows perfect hexagonal structure.
  • TEM Thin Film
  • On SEM image (below), BN is seen as wrinkles on top of the copper foil.

  • SEM Thin Film
  • SAD data of h-BN

  • SAD Data
  • 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.
  • Absorbance data BN on copper

    SEM Thin Film
