Interpretation:
The
Concept introduction:
Semiconductors are devices that have conductivity intermediate between conductors and insulators and their conductivity gets enhances when doped.
Doped semiconductors are used in commercialized electronic devices as diodes, transistors, LEDs, photovoltaic cells. They all differ in their functions and that are as follows:
- Diodes convert alternating current to direct current.
- Photovoltaic cells convert sunlight to electricity.
- LEDs act as a light source.
- Transistors amplify an electrical signal in an integrated circuit.
(b)
Interpretation:
If the light emitted is blue by the device then the substitution of indium in
