Topics in Semiconductor Electronics: Materials, Devices and Simple Circuits

1

1. Classification of Solids and Semiconductor Types

  • Solids are classified on the basis of resistivity or conductivity.
  • Metals have very low resistivity and high conductivity.
  • Semiconductors have intermediate resistivity.
2

2. Intrinsic Semiconductor and Charge Carriers

  • An intrinsic semiconductor is a pure semiconductor without deliberate impurities.
  • At 0 K, an intrinsic semiconductor behaves like an insulator.
  • At temperatures above 0 K, thermal energy breaks some covalent bonds and creates free electrons and holes.
3

3. Extrinsic Semiconductor and Doping

  • Adding a small amount of suitable impurity to a pure semiconductor increases its conductivity manifold.
  • This process is called doping.
  • The impurity atoms are called dopants.
4

4. p-n Junction Formation and Depletion Region

  • A p-n junction is the metallurgical junction between p-region and n-region of a doped semiconductor wafer.
  • It is the basic building block of diodes and many other semiconductor devices.
  • Junction formation involves diffusion and drift.
