Semiconductor Electronics is the most important chapter of CBSE Class 12 Physics. Every year 3-4 questions are asked in CBSE class 12 physics board examination having weightage of about 7 marks. The chapter is very broad and contains many topics & subtopics. We have divided this chapter into three parts. This is the Part -I of these notes where we have provided easy to understand short notes on the following topics and sub-topics:
- Classification of Substances
- On the basis of conductivity
- Classification of Substances
- On the basis of energy band gap
- Intrinsic Semiconductor & Extrinsic Semiconductor
- N-type Semiconductors & P-type Semiconductor
The short notes given below on the above-mentioned topics and sub-topics are very important for board examination as well as competitive examination.
Classification of Substances: On the basis of conductivity
