Unit IV: Semiconductor Materials | BCA 2nd Semester Fundamentals of Electrical and Electronics Notes Pdf

The electrical conductivity of a semiconductor material falls between that of a conductor, such as metallic copper, and that of an insulator, such as glass. Its resistivity decreases as its temperature rises, whereas metals have the reverse effect. Impurities ("doping") can be introduced into the crystal structure to change its conducting characteristics in beneficial ways.

A semiconductor junction is formed when two differentially doped areas in the same crystal occur. Diodes, transistors, and most contemporary electronics are built on the behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions.

In this “Semiconductor Materials – Fundamentals of Electrical and Electronics” you will learn about the following topics:

1. Energy Band Structures Of Conductors
2. Insulators and Semiconductors
3. Fermi Level and Energy Gap
4. Conduction a Principle in Semiconductors
5. Electrons and Holes
6. Donor and Acceptor
7. Impurities N-Type And P-Type Semiconductors
