Karl-Heinz Erdmann,Thomas J. Mageravy mass and low mobility of 3d-electrons (as compared to the values for these parameters in the “conventional” semiconductors), the question arises whether the band model is a legitimate representation of the energy states. Several features of the transition metal compounds have slowed down progres

On the Calculation of Phonon Dispersion Curves in Insulators,The basic features of some wellknown phenomenological force constant models are reviewed. Their interrelation with attempts for ab initio calculations of the phonon-spectrum is discussed. A formal derivation of the dispersion curves in the harmonic Born-Oppenheimer approximation and results of an application of the method to LiF are given.
