Quantum-interference component of the electron diffusion coefficient in a gas
Afonin V. V., Gal'perin Yu. M., Gurevich V. L.
The quantum-interference component of the diffusion coefficient and of the conductivity of electrons in gases is discussed. At room temperature and a pressure of a few atmospheres, this component can reach a relative magnitude of a few tenths of 1%. Interatomic collisions provide an additional mechanism for the phase relaxation of the electron wave function. This mechanism is usually insignificant in a solid.
