Chapter 4: Electrical Behavior
This chapter examines some of the behaviors that suit materials for electrical and electronic applications. It begins by explaining how charge carriers move in metals and semiconductors and how properties such as conductivity, mobility, and resistivity are derived. It discusses the significance of energy bands, intrinsic and extrinsic conduction, and the properties of compound semiconductors. It also covers semiconductor devices, including p-n junctions, light emitting diodes, transistors, and piezoelectric crystals.
