Employing a superposition representation of the density matrix for a fixed energy, the first order quantum corrections to the diffusivity are calculated for independent charge carriers scattered by uncorrelated point-like scatterers. It is shown how fluctuations in carrier density, especially those which are caused by the current itself, contribute to the quantum corrections. Unter Benutzung einer Superpositionsdarstellung fur die Dichtematrix bei fixierter Energie werden fur unabhangige… CONTINUE READING
