Elastic properties of zinc-blende and wurtzite AlN, GaN, and InN Journal of Applied Physics 82 , 2833 (1997); 10.1063/1.366114 Lattice parameters of gallium nitride
1996-02-01 · To provide a basis for understanding future wide energy gap device concepts and applications based on zinc-blende III-V nitride semiconductors, particularly Gal-xAlxN/GaN lattice mismatched heterostructure devices, we have computed the electronic band structure parameters of the zinc-blende GaN, AIN and Gal-xA]xN alloys using the empirical pseudopotential method (EPM)181.
Dependence of the lattice parameters and the energy gap of zinc-blende-type semiconductors on isotopic masses. The dependence of the E 0 direct gap of Ge, GaAs, and ZnSe on isotopic masses at low temperatures has been investigated. Here, the bowing parameter is not constant, it depends on the alloy composition x. Thus, this bowing parameter is given by: C ABC (x) = -0.127 + 1.310 * x (Table XII., I. Vurgaftman et al., J. Appl. Phys.
Density of ZnTe There are 4 anions and cations in the unit cell of ZnTe and it has a lattice parameter a = 0.688 nm. Therefore the volume of the unit cell V = (0.688 x 10-9)3 = 3.25x 10-28m3 The mass per unit cell M = (4*65.39 + 4*127.6)/N ; N =Avogadro Number = 1.28 x 10-21 grams. Therefore we can calculate the density as M/V = 3.94 g/cc d. The data for the lattice parameters are quoted from A R West "Basic Solid State Chemistry" (Wiley 1988), which states them to be from R W G Wykoff, "Crystal Structures" (Wiley 1971) Vol 1. The densities of the zinc-blende structures given in the tables below have been obtained by calculation using the respective lattice parameters from there. and zinc blende lattice is small [11]: DE W-ZB ¼ 18.41meV/atom for AlN, DE W-ZB ¼ 11.44meV/atom for InN, and DE W-ZB ¼ 9.88meV/atom for GaN. Wurtzite form is energetically preferable for all three nitrides compared to zinc blende, although the energy difference is small.

Each of the various lattice parameters are designated by the letters a, b, and c. 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.
