Summary
A method for calculating the density of states of substitutional binary alloys is presented. It essentially consists of successive applications of Beeby'st-matrix formulation of the KKR theory to the single-impurity problem. This method is applied to calculate thed-densities of states of Cu-Ni alloys of various concentration. The results are in reasonable agreement with both experimental photoemission and soft-X-ray emission data and with the theoretical calculations of Stockset al. and Bansilet al. via different approaches.
Riassunto
Si presenta un metodo per calcolare la densità di stati delle leghe binarie sottostituzionali. Esso consiste essenzialmente di applicazioni consecutive della formulazione della matricet di Beeby della teoria KKR al problema di singola impurità. Questo metodo è applicato per calcolare le densitàd di stati delle leghe Cu−Ni di varia concentrazione. I risultati sono in ragionevole accordo sia con i dati sperimentali della fotoemissione che con quelli dell'emissione di raggi X molli e con i calcoli teorici di Stockset al. e Bansilet al. per mezzo di approcci diversi.
