Graphene Brillouin Zone
Graphene () is a carbon allotrope consisting of a Single-layer materials, single layer of atoms arranged in a hexagonal lattice, honeycomb planar nanostructure. The name "graphene" is derived from "graphite" and the suffix -ene, indicating the presence of double bonds within the carbon structure. Graphene is known for its exceptionally high Ultimate tensile strength, tensile strength, Electrical resistivity and conductivity, electrical conductivity, Transparency and translucency, transparency, and being the thinnest two-dimensional material in the world. Despite the nearly transparent nature of a single graphene sheet, graphite (formed from stacked layers of graphene) appears black because it absorbs all visible light wavelengths. On a microscopic scale, graphene is the strongest material ever measured. The existence of graphene was first theorized in 1947 by P. R. Wallace, Philip R. Wallace during his research on graphite's electronic properties, while the term ''graphen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic-scale
Atomic spacing refers to the distance between the atomic nucleus, nuclei of atoms in a material. This space is extremely large compared to the nuclear size, size of the atomic nucleus, and is related to the chemical bonds which bind atoms together. In solid materials, the atomic spacing is described by the bond lengths of its atoms. In ordered solids, the atomic spacing between two bonded atoms is generally around a few ångströms (Å), which is on the order of 10−10 meters (see Lattice constant). However, in very low density gases (for example, in outer space#Environment, outer space) the average distance between atoms can be as large as a meter. In this case, the atomic spacing is not referring to bond length. The atomic spacing of crystalline structures is usually determined by passing an electromagnetic wave of known frequency through the material, and using the laws of Bragg diffraction, diffraction to determine its atomic spacing. The atomic spacing of amorphous solid, amo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
