Bay, fjord, cala, armchairs and zigzag chemists use these terms to describe the shape of the nacre edge. Graphene has a single carbon atom, each of which consists of three carbon atoms. This creates a pattern that reminds a honeycomb, each atom in each corner. Nanographer is a great candidate for microelectronics to move to nanoscale and replace silicon instead.
The electronic properties of the material depend on its shape, size and, above all, its periphery, that is how the edges are structured. The zigzag periphery is particularly suitable for this configuration, which acts as an electron, a carrier of carriages, is more mobile than the other edges. This means that the use of zigzag shaped graphene particles in nanoelectronics is more frequent.
Scientists who want to research only nanographically Zigzag say that this form creates difficult and difficult components for control. It is predicted, however, that if the electronic properties are to be analyzed in detail.
PhD by Konstantin Amsharov, Organic Chemistry II. Professor-led researchers have now achieved this. His research has now been published Nature Communications. In addition to finding a simple method for synthesizing nanograms, the procedure yields around 100 percent and is a good-quality production. Already in the laboratory they have produced a technically important amount.
The researchers produce first molecules when they are joined in a vocational formation carved into some cycles. In the end, the parts of the graphene are located at the center of the honeycomb rows or four flat sheets from the four star sheets, looking for the zigzag pattern on the edges. The product crystallizes directly, even in synthesis. In the solar system, molecules are not contacted with oxygen. In solution, however, oxidation helps to quickly disintegrate the structures.
This approach allows scientists to produce large charts of graphene while keeping shape and control over the periphery. This advance in the study of graphene research should make scientists look to the production and research of the most interesting nanomaterials structures, in order to make use of the use of nanoelectronic material.
