Question
Chapter 12, Problem 12.97SP
Interpretation Introduction
Interpretation:
The band gap required to emit 470 nm wavelength of blue light by an LED is to be determined.
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 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.
