HQ graphene Hexagonal Boron Nitride crystals

Product Name Name:HQ graphene Hexagonal Boron Nitride crystals Product Overview Hexagonal boron nitride is an insulator with a band gap of ~6 eV and has been used extensively as an insulator for the production of ultrahigh mobility 2D heterostructures composed of various types of 2D semiconductors (e.g. WSe2, MoSe2, etc). The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers, down to monolayer h-BN. The h-BN crystals from HQ Graphene have a typical lateral size of ~0.1 cm and are transparent. The monocrystalline h-BN is an excellent insulator which is represented by its very large breakdown voltage (>0.4 V/nm). Large area size h-BN single crystals can be can be exfoliated onto a substrate (eg. SiO2, quartz, polymer, etc). Sizes range up to ~100 μm for crystals with a thickness of a few tens on nm thick. Technical Parameter Diameter: ~1mm Packing: About 20 pieces Appearance: white transparent flake Electrical properties:Insulator Crystal structure:Hexagonal Unit cell parameters:a = b = 0.2502 nm, c = 0.6617 nm, α = β = 90°, γ = 120° Type:Synthetic Purity:Grade A Product characteristics Excellent thermal stability: able to maintain structural stability at high temperatures. Good chemical inertness: stable in most chemical environments. High thermal conductivity: It is a good heat conduction material. Electrical insulation: Excellent electrical insulation performance. Application Fields Insulation and heat dissipation materials:Due to its good electrical insulation and high thermal conductivity, BN can be used as an insulating heat dissipation layer in electronic devices. Deep UV optoelectronics:Boron nitride has a wide band gap and is suitable for deep UV photoappliances. Electronic packaging materials: BN can be added to the polymer matrix to prepare high-performance electronic packaging materials. It can improve the mechanical strength, insulation properties and thermal stability of the material, while not interfering with the normal operation of electronic components.
