Difference between Intrinsic and Extrinsic Semiconductor
1. How do intrinsic semiconductors generate electron-hole pairs?
Intrinsic semiconductors make pairs of electrons and holes when they get hot. When an electron moves around, it leaves a positive hole behind.
2. How do semiconductors differ from conductors and insulators?
Semiconductors are a bit different from conductors, which easily carry electricity, and insulators, which block it. Semiconductors have a medium level of conductivity. They can be controlled to conduct or insulate, making them vital for electronics.
3. Why are N-type semiconductors good conductors?
N-type semiconductors get extra electrons added through doping, which gives them a lot of charge carriers. These extra electrons enhance their conductivity and ability to carry current.
4. What makes intrinsic semiconductors suitable for photovoltaic applications?
Intrinsic semiconductors make pairs of electrons and holes when they get light. We use this in things like solar panels to change light into electricity.
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.
