FAQs on Semiconductor and its types Video Lecture - Modern Physics for IIT JAM

1. What is a semiconductor?
Ans. A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. It can conduct electricity under certain conditions but not as effectively as a conductor.
2. What are the different types of semiconductors?
Ans. There are two main types of semiconductors: intrinsic and extrinsic. Intrinsic semiconductors are pure semiconducting materials, while extrinsic semiconductors are doped with impurities to alter their electrical properties.
3. How do semiconductors work?
Ans. Semiconductors work based on the movement of electrons. When a voltage is applied, electrons can move from one energy level to another, creating a flow of current. The behavior of electrons in semiconductors can be controlled by doping or applying external factors such as temperature.
4. What are some common applications of semiconductors?
Ans. Semiconductors are used in various electronic devices such as transistors, diodes, integrated circuits, and solar cells. They are also essential components in computers, smartphones, televisions, and many other electronic systems.
5. What are the advantages of using semiconductors?
Ans. Semiconductors offer several advantages, including small size, low power consumption, high operating speeds, and the ability to control and amplify electrical signals. These properties make them crucial for modern electronics and enable the development of advanced technologies.
