摘要
The phonon dispersions and their related properties are computed in polytype materials by using a semi-empirical approach called adiabatic bond charge model. Both hexagonal 2H and cubic 3C phases of Silicon and Germanium are investigated in terms of heat capacity, Raman shift and sound velocities for each phonon branch in all main directions.
