As with all materials, engineering semiconductors primarily involves formation of alloys and control of defects. Defect engineering is discussed in detail in Chapter 7. This chapter considers the basics of alloying. The objective is usually to control the optoelectronic properties of the semiconductor, primarily through its energy band structure. Other properties change as well and some of these, such as lattice constant, are important to producing a high-quality material, as we shall see in Chapter 7.
