Lattice dynamics of tantalum: A pseudopotential approach

Динамика решетки тантала. Псевдопотенциальный подход

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

The phonon dispersion of tantalum is calculated by means of a transition metal model potential. By the potential approach of the present model, most of the anomalies in the phonon dispersion curves have been explained. Comparison of our results with the experimental ones shows a fair agreement.

Riassunto

Si calcola la dispersione fotonica dei tantali mediante un potenziale modello del metallo di transizione. Mediante l’approccio del potenziale dell’attuale modello, è stata spiegata la maggior parte delle anomalie nelle curve di dispersione fononiche. Il confronto dei nostri risultati con quelli sperimentali mostra un buon accordo.

Резюме

Используя модельный потенциал для переходных металлов, вычисляется дисперсия фононов в тантале. В рамках предложенного потенциального подхода объясняется большинство аномалий в дисперсионных кривых фононов. Сравнение полученных результатов с экспериментальными обнаруживает удовлетворительное согласие.
