ACS Material Hexagonal Boron Nitride (h-BN) on Si/SiO2

Product Name Name:Buckyusa Multiwall Nanotubes-OH Hydroxy Product Overview Boron nitride film is a two-dimensional material composed of alternating boron and nitrogen atoms with a graphene-like honeycomb lattice structure. It inherits the excellent properties of boron nitride bulk materials, including mechanical, electrical, thermal and optical properties, and has more characteristics and wider application prospects due to its special two-dimensional structure. The CVD method is to deposit a boron nitride film by introducing a gas or steam containing boron and nitrogen into the reaction chamber to undergo a chemical reaction on the substrate surface. This method can achieve high density and high quality film deposition at a lower temperature, and the thickness, crystallinity and morphology of the film can be controlled by adjusting the reaction conditions. Product Features Excellent insulation: Boron nitride itself is a good electrical insulator, and the boron nitride film prepared by CVD inherits this property, and its resistivity is very high. Good thermal stability and high thermal conductivity: The structure and properties of CVD boron nitride film remain stable at high temperature. It has a high thermal conductivity, between tens and hundreds of W/(m·K) (the specific value will vary due to factors such as the quality and structure of the film). This high thermal conductivity enables it to efficiently conduct heat away from the heat source, which is of great value in heat dissipation applications. Chemical stability: CVD boron nitride film is inert to most chemical substances and is not easy to react with acids, bases, organic solvents and so on. High surface smoothness: The boron nitride film prepared by the CVD method usually has a relatively smooth and flat surface. High purity of omposition: A relatively pure boron nitride film with low impurity content can be prepared by CVD method. This helps to give full play to the excellent properties of boron nitride material itself and reduce the performance defects caused by impurities. Application Fields Electronic devices: Boron nitride films have good insulation properties and high temperature stability, and can be used for isolating layers and thermal management applications in electronic devices. Optical devices: Boron nitride films have good transmittance in the visible and ultraviolet regions and can be used in optical devices and optical coatings. Thermal interface materials: Because of its excellent thermal conductivity, boron nitride films can be used to prepare thermal interface materials and heat sinks. Nanomechanical system: boron nitride film has good mechanical strength and chemical stability, which is suitable for the manufacture of nanomechanical systems.
