Types of Semiconductors
Semiconductors are classified into intrinsic (pure) and extrinsic (doped) types. Doping introduces impurities into the semiconductor to alter its electrical properties, creating n-type and p-type materials.

1: What is the difference between an intrinsic and an extrinsic semiconductor?
An intrinsic semiconductor is pure, without any significant impurities. An extrinsic semiconductor has been doped with impurities to improve its electrical properties.
2: How do you determine the type of semiconductor formed by doping?
The type of semiconductor formed depends on the dopant used. If the dopant has more valence electrons than the semiconductor, it forms an n-type. If it has fewer valence electrons, it forms a p-type.
3: How can I improve my understanding of semiconductor devices?
Practice solving a variety of problems, use visual aids to understand the concepts and relate theoretical knowledge to practical applications to deepen your understanding.
