German texts dominated the 19 th century literature on the history of crystallography, especially those of Marx (1794-1864) and Kobell (1803-1882). Marx’s Geschichte der Kristallkunde (1825) was valued by Shafranovskii because of its … WebAug 28, 2024 · All the atoms in a zinc blende structure are 4-coordinate. The zinc blende unit cell is shown in Figure 7.1.9. A number of inter-atomic distances may be calculated for any material with a zinc blende unit cell using the lattice parameter (a). Zn − S = a√3 4 ≈ 0.422a. Zn − Zn = S − S = a √2 ≈ 0.707 a.
