Structural, free-charge carrier and phonon properties of zinc-blende

Illustration of how the zinc-blende energy levels (solid lines) are modified by rules (a)— (c) (vertical arrows) to yield the wurtzite energy levels (dashed lines). Types I and II are direct (D) in zinc-blende structure while types III, IV, and V are indirect (I) in zinc-blende structure. Types I and V are Zinc blend has four ions and four ions per unit cell. We have radius of as 0.083 nm and radius of ions is 0.174 nm. Now, use equation (2) to calculate volume.
