Problems

1. 1.1 Using Appendix III, which of the listed semiconductors in Table 1–1 has the largest band gap? The smallest? What are the corresponding wavelengths if light is emitted at the energy E_g? Is there a noticeable pattern in the band gap energy of III–V compounds related to the column III element?

2. 1.2 For a bcc lattice of identical atoms with a lattice constant of 5 Å, calculate the maximum packing fraction and the radius of the atoms treated as hard spheres with the nearest neighbors touching.

3. 1.3 Label the planes illustrated in Fig. P1–3.
