Semiconductors are materials with electrical conductivity between conductors and insulators, with examples like silicon and germanium. they can be intrinsic (pure) or extrinsic (doped with impurities) and are essential in devices such as diodes and transistors.
Semiconductor Class 12 Notes Pdf In this topic, we will explore the world of semiconductors. it's a journey from what semiconductors are all the way to creating building blocks of these computers. In this chapter first, we will discuss the band theory of solids. then we will discuss junction diode and transistors. after that, we will explore the basics of logic gates. in the end, we will take the elementary idea of integrated circuits. The document discusses semiconductors and their properties. it begins by explaining that semiconductors have a smaller bandgap than insulators, allowing electrons in the valence band to jump to the conduction band with external energy. A semiconductor is a substance whose resistivity lies between the conductors and insulators. the property of resistivity is not the only one that decides a material as a semiconductor, but it has few properties as follows.
