What this chapter is about
Semiconductors are materials with electrical conductivity between conductors (metals) and insulators. Silicon and germanium are fundamental semiconductors that form the basis of modern electronics. Unlike metals (always conducting) or insulators (never conducting), semiconductor conductivity can be controlled through doping and applied voltage. The ability to switch and amplify electrical signals using semiconductors has revolutionized technology, enabling transistors, integrated circuits, and digital electronics. This chapter explores semiconductor physics, device operation, and basic circuit applications.
