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.
The space group of the Zincblende structure is called F 4 3m (in Hermann–Mauguin notation), or 216. [50] [51] The Strukturbericht designation is "B3". [52] The Zincblende structure (also written "zinc blende") is named after the mineral zincblende , one form of zinc sulfide (β-ZnS). As in the rock-salt structure, the two atom types form two ...
In Hermann–Mauguin notation, space groups are named by a symbol combining the point group identifier with the uppercase letters describing the lattice type.Translations within the lattice in the form of screw axes and glide planes are also noted, giving a complete crystallographic space group.
These are the crystallographic groups of a cubic crystal system: 23, 432, 2 / m 3, 4 3m, and 4 / m 3 2 / m . All of them contain four diagonal 3-fold axes. These axes are arranged as 3-fold axes in a cube, directed along its four space diagonals (the cube has 4 / m 3 2 / m symmetry). These symbols are ...
Synthetic diamonds of various colors grown by the high-pressure and high-temperature technique, the diamond size is ~2 mm. Infrared absorption spectrum of type IaB diamond. (1) region of nitrogen impurities absorption (here mostly due to the B-centers), (2) platelets peak, (3) self-absorption of diamond lattice, (4) hydrogen peaks at 3107 and ...
Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties. [1] DLC exists in seven different forms. [2] All seven contain significant amounts of sp 3 hybridized carbon atoms.
