The lattice dynamics of zinc-blende GaN and AlN were studied theoretically using a two-parameter Keating potential together with the long-range Coulomb interactions. Phonon frequencies transformed from those of the wurtzite counterparts were used to determine the
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. θ = cos-1 1 3.

A number of inter-atomic distances may be calculated for any material with a zinc blende unit cell using the lattice parameter (a). lattice. For Gallium phosphide (GaP) lattice constant ’a’ is 5:45”A. The lattice constant of a semiconductor can expand or contract when impurity atoms are incorporated.

The energy lattice parameters graphs were presented in figure 3 for Zinc blende (B3), Rock salt (B1) and Wurtzite (B4) in the same graph. The lattice parameters were obtained to be 10.3, 9.6 and 7.3 (a.u) for Zinc blende, Rock salt and Wurtzite respectively. The ground-state properties of the rock-salt, Zinc blende

Related content Structural and magnetic properties of CrSb compounds: NiAs structure S Polesya, G Kuhn, S Mankovsky et al.- The lattice parameter has a stronger influence on the minimum energy losses in channeling of zinc-blende compounds than the A or Z of the host-lattice atoms. The Z dependence of incident light ions channeled in a given host lattice is the same as that for normal energy losses.
