General Description 

Hexagonal boron nitride (h-BN) monolayer film has a similar lattice structure to graphene, with a lattice mismatch of only about 1.8%. h-BN and graphene are different in terms of their electrical conductivity. With a bandgap of 6.08 eV, h-BN has an insulating nature, whereas graphene is considered a semi-metal.

h-BN is widely used as a dielectric substrate in electronic and optical devices for graphene and other 2D-layered semiconductors (e.g. transition metal dichalcogenides (TMDs)).

High-quality h-BN monolayer film is available on 2 different substrates: SiO2/Si PET (polyethylene terephthalate). Different sizes and substrates of monolayer h-BN films are also available via custom order.

  • Glass (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
  • Sapphire (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
  • Silicon (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
  • Quartz (1 cm × 1 cm, 1 cm × 2 cm, 2 cm × 2 cm or custom-made sizes)
  • Copper (5 cm × 10 cm or custom-made sizes)

 

Applications

Due to its special chemical properties and electronic structure, h-BN often serves
as an atomic flat insulating substrate or a tunneling dielectric barrier in graphene and other 2D electronics. Like graphene, h-BN exhibits excellent mechanical flexibility, chemical and temperature stability, and high thermal conductivity. h-BN has been used as a protective membrane in devices such as deep ultraviolet and quantum photonic emitters, where it provides strong oxidation resistance. It has also been utilised as a tunnelling barrier in field-effect tunnelling transistors.

Synthesis

High quality monolayer h-BN films were first grown directly on copper foil via the chemical vapour deposition (CVD) method. The films were later transferred to the desired substrates via the wet chemical transfer process.

Usage

h-BN monolayer film is ready to use in various research purposes, such as microscopic analysis, photoluminescence, and Raman spectroscopy studies. h-BN monolayer film can also be transferred to other substrates.
