The Program Package Unisoft
The lattice dynamical program package UNISOFT has been developed as a tool for phenomenological model calculations and optimisation of experiments. The new windows based version offers an easy way to calculate and display modes of lattice vibrations:
-
Determination of symmetry coordinates, independent interactions and pair
correlations
-
Definition of the structure either by spacegroup or by
individual position of all atoms within the unit cell
-
Visualisation of the first Brillouin-zone
-
Uniform distribution of phonon wavevectors over the whole Brillouin-zone for density of states
-
Calculation of eigenfrequencies and eigenvectors of the lattice vibration
-
Plot of the phonon-dispersion surface
-
Calculation and visualisation of structure factors
-
Visualisation of the eigenvectors and eigenfrequencies of the lattice vibrations
