Key Concepts Covered in Semiconductor Devices Text Books

Fundamentals of Semiconductor Physics

Before delving into devices, it’s essential to grasp the fundamentals of semiconductor

physics. This includes understanding intrinsic and extrinsic semiconductors, energy bands,

and charge carriers (electrons and holes). Textbooks usually start by explaining the

concept of the energy bandgap, which determines a material’s electrical characteristics.

For example, silicon’s bandgap is about 1.1 eV, making it suitable for a variety of
