Classification of Semiconductors – Class 12 Physics Notes with Examples
Understanding Semiconductors: Band Gaps, Types, and Doping Introduction A Semiconductor is a material whose conductivity lies between that of conductors and insulators. Semiconductors play a central role in modern electronics. Their behavior depends heavily on factors such as energy band gaps, material purity, and temperature. This blog presents a complete explanation of semiconductors, including classifications, intrinsic and extrinsic types, and how doping affects their properties.
