Electronic guidance
Electron conductance (conductivity type n) - a type of electrical conductivity in which electrons are the carrier of electric charge. In the band model of crystalline solids, the phenomenon is that electrons occupying quantum states within the conduction band move to adjacent unoccupied quantum states within this band in the direction opposite to the direction of the electric field vector.
The electron conductance shows: Electron conductivity in metals
In metals, electrons of conductance are valence electrons of particular atoms. In the crystal lattice, they break away from their atoms and begin to move freely in the entire volume of metal, creating so-called electron gas. The concentration of electrons of conductivity in metals does not depend on temperature, while the mobility of electrons decreases with increasing temperature (due to specific friction caused by electron collisions with non-harmonic crystal lattice), which consequently reduces the electrical conductivity. Ohm's law is met for metals.
