CBSE Class 12 Physics Chapter 14 Semiconductor Electronics NCERT Solutions

There is a whole new world of materials other than metals and non-metals, popularly known as the semiconductor materials. They define the new cutting-edge technologies used in today’s world electronic devices. Interesting huh? Let’s study about the types of semiconductors, p-n n junction diodes, logic gates and transistor applications in the topics below:

Some Concepts & Definitions from CBSE Class 12 Physics Chapter 14 Semiconductor Electronics

Q.1. What are the different types of Semiconductors?

Broadly speaking, there are three types of semiconductors:

  1. Elemental semiconductors: Semiconductors comprising of a single fourth group element. Examples: Si and Ge.
  2. Compound semiconductors: Semiconductors made of compounds of two or more elements. These can be further classified into:
  • Inorganic: CdS, GaAs, InP, etc
  • Organic: anthracene, doped phthalocyanines, etc
  • Organic polymers: polypyrrole, polyaniline, etc

Q.2. Define Valence Band and Conductor Band

The valence band is the energy band consisting of valence (tightly-bound) electrons. The conduction band is the energy band consisting of conduction (loosely-bound) electrons.

Note:
1. Without any external energy, all electrons lie in the valence band.

2. For metals, conduction band, and valence band overlap.

3. In Si, outer orbit comprises of 2s, + 2p electrons. These 4 electrons have 8 available energy states of which 4 are in the valence band and 4 in the conduction band.
