LMTO-ASA Calculations on NiSi_2/Si(001) Interface

元データ 1991-08-15 社団法人日本物理学会

概要

The electronic structure of the NiSi./ Si(001) interface was studied using LMTO-ASA (linear muffin-tin orbitals in the atomic sphere approximation) based on the density functional formalism. We examined two interface structures in which the Niatoms at the interface are sixfold-coordinated or eightfold-coordinated. The sixfoldstructure had a negative Schottky barrier height (E. -E.). The eightfoldNiSi./ Si(001) structure showed almost the same Schottky barrier height as the Type-A NiSi./Si(III) interface despite the difference in the interface atomic structure.
