1.1 Silicon density = 2.33 g/cm3.
1 mole = 28 g
(2.33 g/cm3)(1 mole / 28 g)(6.02×1023 / mole) = 5×1022 cm-3
8/a3 = 5×1022 cm-3
a = 5.5×10-8 cm = 5.5 Å

1.2 Germanium a = 5.66 Å = 5.66×10-8 cm.
Density = 8/a3 = 4.4×1022 cm-3


1.3 Strontium titanate (SrTiO3) has the perovskite structure.
(a) Unit cube with the atoms:




(b) Each Ti atom is bonded to 6 O atoms.
(c) Molecular mass = 183.49u
a = 3.9 Å
Number density = 1/a3 = 1.69×1022 cm-3
(1.69×1022 / cm3)(183.49 g / mole)(1 mole / 6.02×1023) = 5.14 g/cm3

1.5 An intrinsic semiconductor has no defects, or few enough to not affect its properties
significantly. An extrinsic semiconductor’s properties are determined by defects.
