Computes dispersion curves and density of states of bulk silicon and silicon nanostructures.
Energy quanta of lattice vibrations (phonons) of silicon structures are characterized by their wave vectors and frequency. Using the Environment-Dependent Interatomic Potential (EDIP) under the harmonic approximation, this application computes dispersion curves (curves of frequency vs. wave vector module) for a given crystallographic direction, and density of states or DOS (number of available states per unit volume at a given frequency per unit frequency interval).
