Name: Monolayer monocrystalline Graphene on SiO2/Si


Product Overview

Monocrystalline graphene is a graphene material with a single crystal structure. Graphene itself is a two-dimensional material composed of a single layer of carbon atoms, while single-crystal graphene emphasizes the highly ordered arrangement of its atoms and the absence of defects, which gives it more excellent physical properties. There are a variety of preparation techniques for single crystal graphene, mainly including the following methods: vapor deposition (CVD), mechanical stripping, epitaxial growth method. This product is prepared by mechanical stripping, also known as the "tape stripping method", which was first proposed by Novoselov et al in 2004 when preparing single-layer graphene. This method uses the friction and relative motion between the tape and the block material to make the thin layer fall off from the block, and uses the adhesive force of the tape to overcome the weak van der Waals force between molecular layers, so as to realize the separation of layer from layer. This method has a low yield, but can obtain high purity single layer graphene. Graphene is separated from graphite by mechanical force and is suitable for laboratory research.

Product Features

 

High electrical conductivity: Due to the absence of grain boundaries and defects, the transmission of electrons in single crystal graphene is smoother, and the electrical conductivity is significantly improved.

High thermal conductivity: Also thanks to its perfect structure, monocrystalline graphene has excellent thermal conductivity.

High quality optical characteristics: low distortion optical transmission can be achieved, which provides the possibility for the preparation of optical devices.

High strength: The ordered arrangement of a single layer of carbon atoms gives single crystal graphene a high mechanical strength.

 

Application Fields

 

Electronics: Because of its high electrical conductivity and high-quality optical properties, single crystal graphene is of great value in the preparation of electronic devices. For example, it can be used to manufacture high-speed electronic devices, photodetectors, etc.

Energy: In the field of energy storage, single crystal graphene can be used to improve the energy density and cycle stability of batteries. In addition, its excellent thermal conductivity also helps in the thermal management of the battery.

Information technology: In the field of information technology, single crystal graphene can be used to prepare high-performance sensors, transistors and other components.

Biomedical: Its unique physical and chemical properties make it also have potential applications in the biomedical field, such as drug carriers, biosensors, etc.

Skin 1004 moisturizer
Best skin care out there. It is not greasy. It makes your skin feel heavenly. There’s very little fragrance to it, and it is compatible with any skin type in my opinion. Great addition to any skin care routine!
