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.

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.
