Intrinsic Semiconductor
Intrinsic Semiconductors are pure semiconductors like silicon, germanium, and carbon. They do not have contaminations therefore they do not carry a lot of charge. This scarcity of charge carriers bestows intrinsic semiconductors with distinct characteristics:
- Electron-Hole Pairs: In intrinsic semiconductors, heat can make pairs of electrons and holes. This happens when an electron moves from one part to another, leaving behind a positively charged hole.
- Limited Conductivity: Intrinsic semiconductors don’t conduct electricity well because they have few charge carriers, which means they’re not great for everyday electronics.
- Temperature Dependence: As temperature rises, more electron-hole pairs are generated, and conductivity increases.
- Photovoltaic Applications: Intrinsic semiconductors are used in photovoltaic devices like solar panels. When light hits them, they make electricity by creating electron-hole pairs.
Difference Between Intrinsic Semiconductor and Extrinsic Semiconductor
Semiconductors are unique materials that possess moderate conductivity, falling between conductors and insulators. The conductivity of semiconductors proves incredibly advantageous for various applications. When we add energy to semiconductors, like heat or light, it makes some particles move around. This creates empty spots that act like positive charges known as holes. This lets electrons move and electricity flow. Transistors, integrated circuits, and diodes are made from semiconductors, which are useful. They can also be switches, amplifiers, and memory cells. They’re like the important parts that make computers, phones, and many other cool things that have changed our world.
