The piezoelectric transduction is based on the conversion of mechanical vibrations into electrical signals and vice versa. The piezoelectric effect…
When light strikes a semiconductor p-n junction, its energy is absorbed by electrons. Electrons and holes generated by light in…
Laser diodes are PN junction devices under a forward bias. LASER is an acronym for Light Amplification by Stimulated Emission…
A photoelectric effect is any effect in which light energy is converted to electricity. When light strikes certain light-sensitive materials,…
Quantum computers employ the laws of quantum mechanics to process data. Quantum mechanics in itself is the study of matter…
Metals have a large number of weakly bound electrons in what is called their conduction band. When an electric field…
Photons are the elemental units of electromagnetic spectrum. For example, white light is composed of a number of different kinds…
What is Magnetism? Magnetism is the force exerted by magnets when they attract or repel each other. This magnetism force…
It was discovered in 1939 that a toroidal cavity made of conductive material called a cavity resonator surrounding an electron…
