In the physics field of semiconductors and insulators, the conduction band is the range of electron energy, higher than that of the valence band, sufficient to make the electrons free to accelerate under the influence of an applied electric field and thus constitute an electric current. Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. A semiconductor' is a Solid material that has Electrical conductivity in between a conductor and an insulator; it can vary over that An insulator, also called a Dielectric, is a material that resists the flow of Electric current. The electron is a fundamental Subatomic particle that was identified and assigned the negative charge in 1897 by J In Physics and other Sciences energy (from the Greek grc ἐνέργεια - Energeia, "activity operation" from grc ἐνεργός In Solids the valence band is the highest range of Electron energies where electrons are normally present at Absolute zero. In Physics, the space surrounding an Electric charge or in the presence of a time-varying Magnetic field has a property called an electric field (that can Electric current is the flow (movement of Electric charge. The SI unit of electric current is the Ampere. Semiconductors may cross this conduction band when they are excited.
