Silicon (Si) has the diamond and GaAs has the zinc blende crystal structures. Given the lattice parameters of Si and GaAs, a = 0.543 nm and a = 0.565 nm, respectively, and the atomic masses of Si, Ga and As as 28.08 g/mol, 69.73 g/mol and 74.92 g/mol, respectively, calculate the density of Si and GaAs. What is the atomic concentration (atoms per unit volume) in each crystal?
