Die Streuung von Leitungselektronen an Fehlstellen in Metallen nach der Pseudopotential Methode
The transition probability for the scattering of conduction electrons at point defects in metals is calculated using the pseudo potential representation for two different pseudo potentials. This expression is then applied to the calculation of the electrical resistivity $\Delta \varrho$ for vacancie...

520 | |a The transition probability for the scattering of conduction electrons at point defects in metals is calculated using the pseudo potential representation for two different pseudo potentials. This expression is then applied to the calculation of the electrical resistivity $\Delta \varrho$ for vacancies in Cu, Ag, and Au using the single orthogonalized plane wave (1-0PW) method. A screened Coulomb potential is taken as the defect potential, and the screening constant is determined by FRIEDEL's sum rule. The results for Cu, using the effective mass m* = m, are $\Delta \varrho$= 1.46 $\mu \Omega$cm/at.%, and $\Delta \varrho$ = 1.70 $\mu \Omega$cm/at.%. The use of m* = 1.4 m for Cu and m* = m for Ag and Au gives unreasonable values for il g, due to an attraction which is caused by the 1 s electrons in the pseudo potential, and not fully compensated by the defect potential. Using the 1-PW method (i. e. no pseudo potential) and m* = m the results for Cu, Ag, and Au are 1.73 $\mu \Omega$cm/at.%, 2.07$\mu \Omega$cm/at.% and 2.11 $\mu \Omega$cm/at.o/o, respectively. | ||
