🔍 Definition of a Semiconductor

A semiconductor is a material that has electrical conductivity between that of a conductor (like copper) and an insulator (like glass). Their ability to conduct electricity can be manipulated by adding impurities (doping) or by applying external factors like heat or light.

Key Materials:

  • Silicon (Si): The most common material used in the industry.
  • Germanium (Ge): One of the earliest semiconductor materials.
  • Gallium Nitride (GaN): Increasingly used in high-power and high-frequency applications.

🛠 Why Are Semiconductors Important?

Semiconductors are the building blocks of all modern electronic devices. Their primary functions include:

  1. Switching: Controlling the flow of current (On/Off) at incredibly high speeds.
  2. Amplification: Strengthening weak electrical signals.
  3. Energy Conversion: Converting light into electricity (Solar cells) or electricity into light (LEDs).
