On the relationship between the phonon anomalies and the ab initio calculated Fermi surfaces of TaC and NbC
- 1. Naval Research Lab., Washington, D.C. (USA)
Description
First principles augmented plane wave calculations show that the Fermi surfaces of TaC and NbC contain flat parallel sheets, while that of HfC is relatively 'normal'. The phonon anomalies in the former two materials are shown to stem from specific transitions across the Fermi surface. (author)
