Question

A certain crystal has lattice parameters of 4.24, 10.00 and 3.66 Å on X, Y, Z axes respectively. Determine the Miller indices of a plane having intercepts of 2.12, 10 and 1.83 Å on the X, Y and Z axes.

(b) Calculate the miller indices for the plane with X, Y, Z intercepts of 2, - 3 and 4 the along the crystallographic axes.

(c) Germanium (Ge) has the diamond cubic crystal structure as shown in Figure 1. It has an FCC lattice with a lattice constant of a = 5.64 Å. Calculate the atomic density of Ge in atom/cm3.
