Understanding Semiconductors

What are the two main types of semiconductors?

• Intrinsic and extrinsic semiconductors

• Organic and inorganic semiconductors

• Conductive and non-conductive semiconductors

• Superconductors and insulators

Name three common semiconductor devices.

• Capacitor

• Resistor

• Diode, Transistor, Integrated Circuit

• Inductor

What is the purpose of doping in semiconductors?

• The purpose of doping in semiconductors is to enhance their electrical conductivity by introducing charge carriers.

• To improve thermal conductivity of materials.

• To create a barrier for electron flow.

• To reduce the size of semiconductor devices.

List two applications of semiconductors in everyday technology.

• Refrigerators and microwaves

• Washing machines and dryers

• Smartphones and computers.

• Televisions and radios

Explain the concept of band gap in semiconductor physics.

• The band gap is the energy difference between the valence band and conduction band in semiconductors, influencing their electrical conductivity.

• The band gap is the amount of current flowing through a semiconductor.

• The band gap is the physical size of a semiconductor material.

• The band gap is the temperature at which a semiconductor operates.
