Epitaxy of Semiconductors: Introduction to Physical Principles

Sphalerite can have Spinel Law twins, where the twin axis is [111]. Many III-V semiconductors such as GaAs, AlsAs, InAs, or InP are of zinc-blende type. In Figure 3.4 the diamond structure is depicted. The primitive basis vectors and the two atoms at and are highlighted in Figure 3.4b.

The rate constants of the homogeneous first-order process fit the Arrhenius uptake and hydration and this makes metals as Pb, Cu, Cr and Zn less mobile.

For materials which are not known to the database and for the use of nondefault values for some of the parameters of a known material. For totally unknown materials, all parameters must be specified in the input file. This will be required in very rare cases, however. If the two basisatoms are different, the structure is called the zinc-blende structure. ManyIII-V semiconductors such as GaAs, AlsAs, InAs, or InP are of zinc-blende type.

The ionic radius of the zinc(II) ion is 0.74 angstroms and that of the sulfide ion is 1.70 angstroms. The ratio of radii for the cation and anion is thus r+/r- = 0.74/1.70 = 0.44. Si has the diamond and GaAs has the zinc blende crystal structure.

If two sides are equal, such as in a tetragonal lattice, then the lengths of the two lattice parameters are designated a and c, with b omitted. The angles are designated by the Greek letters α, β, and γsize 12{γ} {}, such that an angle with a specific Greek letter is not subtended by the axis with its Roman equivalent. The reported values of the lattice parameter of zinc-blende MgTe were determined mainly by extrapolation from X-ray diffraction data on Cd 1−x Mg x Te bulk and layered , , ternary compounds. The extrapolated values varied from a =6.35 Å [2] to a =6.435 Å [1] . a = 4 3 l. The way that I started my derivation was saying that each tetrahedron has a sulfide ion in the center, so then we can make a triangle from the center point, and two zinc adjacent atoms. This isosceles triangle will have an angle.


The densities of the zinc-blende structures given in the tables below have been obtained by calculation using the respective lattice parameters from there. There are four molecules in a unit cell of the zinc--blende lattice. If an accurate lattice constant is aail-v able, the calculation of g gives in principle a good, reli-able alue.v orF BN each B (N) has four nearest neighbors of B (N) at a distance of √ 3a0=4 at the corners of a regular tetra-hedron.
