Semiconductors and Logic Gates - Class 12 Physics | JEE Mains & Advanced Semiconductors and Logic Gates - Class 12 Physics | JEE Mains & Advanced Semiconductors are foundational to modern electronics, forming the basis of devices like diodes, transistors, and logic gates. This article explores semiconductors and logic gates, covering concepts, derivations, and applications in depth. What are Semiconductors? Semiconductors are materials whose electrical conductivity lies between conductors and insulators. They are primarily made of silicon (Si) and germanium (Ge) and exhibit unique properties due to their energy band structure. Types of Semiconductors Semiconductors are classified as intrinsic and extrinsic. These types, along with their doping processes, determine their conductivity and applications in electronics. Logic Gates Logic gates are electronic circuits that perform logical operations...
