Question

Which of the following is/are the applications of semiconductors?

• A. Used for making electronic components
• B. Used for making diodes
• C. Used for making transistors
• D. Used for making solar panels

Answer 1

Answer: (A), (B), (C), (D)

Used for making solar panels

Applications of p-type and n-type semiconductors:
1. Used for making electronic components
2. Used for making diodes which is a combination of n-type and p-type semiconductors and is used as a rectifier.
3. Used for making transistors which contains n-p-n and
p-n-p junctions to amplify radio and audio signals.
4. Used for making solar cell which is an efficient photo-diode. These are used for conversion of light energy into electrical energy.
5. The solid state materials are produced by combination of elements of groups 13 and 15 compound.
E.g. $InSb,AlP,GaAs$.
6. The solid state compounds are obtained by combination of elements of groups 12 and 16 compounds.
E.g. $ZnS,CdS,CdSe\text{and}HgTe.$

Thus, all the given statements are correct.
