Diamond cubic - Wikipedia
In crystallography, the diamond cubic crystal structure is a repeating pattern of 8 atoms that certain materials may adopt as they solidify. While the first known example was diamond, other elements in group 14 also adopt this structure, including α-tin, the semiconductors silicon and germanium, and silicon–germanium alloys in any proportion.
Diamond crystal structure - TU Graz
Diamond is a crystal structure with a face centered cubic Bravais lattice and two atoms in the basis. Carbon, silicon germanium, and α-tin form this crystal structure. Crystal structure: Diamond Bravais lattice: face centered cubic Space group: 227 (F d …
Diamond Cubic Unit Cell – Materials Science & Engineering
2022年11月24日 · The diamond cubic crystal structure is based on the face-centered cubic Bravais lattice (you can imagine it as two FCC unit cells, offset by ¼). There are 8 atoms per unit cell, and each atom is tetrahedrally coordinated so that it has 4 nearest neighbors. DC is a famously strong crystal structure, and is the structure of diamond.
3.4 Basic Properties of the Diamond Structure - TU Wien
Figure 3.4: (a) Crystallographic unit cell (unit cube) of the diamond structure. (b) The primitive basis vectors of the face centered cubic (fcc) lattice and the two atoms forming the basis are highlighted. In cubic semiconductors such as Si or Ge the two atoms of the basis are identical and the structure is called the diamond structure.
Diamond Structure - Physics in a Nutshell
Conventional unit cell of the diamond structure: The underlying structure is fcc with a two-atomic basis. One of the two atoms is sitting on the lattice point and the other one is shifted by $\frac{1}{4}$ along each axes. This forms a tetrahedrical structure where each atom is surrounded by four equal-distanced neighbours.
Diamond Crystal Structure - Columbia University
The diamond lattice is composed of two interpenetrating fcc lattices, one displaced 1/4 of a lattice constant in each direction from the other. Each site is tetrahedrally coordinated with four other sites in the other sublattice.
lattice. In the crystal each ion is surrounded by 6 nearest neighbors of the opposite charge. The space lattice is fcc, and the basis has one Na+ at ½(111) and Cl at (000). The figure shows one conventional unit cell. The ionic diameters here are reduced in relation to the cell in order to clarify the spatial arrangement. Basic Concepts
Structure of Diamond - Steve Sque
The crystal structure of diamond is equivalent to a face-centred cubic (FCC) lattice, with a basis of two identical carbon atoms: one at (0, 0, 0) and the other at (1/4, 1/4, 1/4), where the coordinates are given as fractions along the cube sides.
The diamond crystal lattice (see Fig. 1) may be described in terms of positions of the carbon atoms. It contains two superimposed FCC (face-centered cubic) sublattices.
The structures, synthesis, properties, and applications of diamond ...
Diamond is described as a solid form of the element carbon with its atoms arranged in a crystal structure called 'cubic diamond' in many dictionaries. The structure of diamond is not only limited to the cubic structure, but also extends to other structures, such as hexagonally structured diamond, nanotwinned diamond, and triclinic diamond ...
