ABSTRACT

In Chapter 6, we will discuss several semiconductor devices utilizing a metal-semiconductor junction, semiconductor-semiconductor junction, and semiconductor-dielectric interface. The devices of interest are Schottky/ohmic contacts, light-emitting diodes (LEDs), and several transistors. The solar cell is another very important device based on the p-n junction of the semiconductor, and we will briefly study it in this chapter after we discuss the optical properties of materials. In addition to our coverage in this chapter, the optical aspect of LEDs will also be reviewed in Chapter 8. This combined knowledge regarding semiconductors and optical materials will help readers better understand solar cells and LEDs more effectively.
