Abstract
A comparative study of the visible and near infra-red reflectivity of nickel and its silicides (Ni4Si, Ni2Si, NiSi and NiSi 2) is presented. The observed structures are interpreted by comparison with valence band density of states measured by X-ray photoemission and published band structure calculations.
Résumé
Nous présentons une étude comparative de la réflectivité du nickel et de ses siliciures (Ni4Si, Ni2Si, NiSi et NiSi2) dans le domaine visible et proche infra-rouge. Une interprétation des structures observées est obtenue par comparaison avec les densités d'états de bande de valence mesurées par photoémission X et les calculs de structure de bande publiés.
