Abstract

The 1D atom chain with the multi-neighbor interactions is studied as a simplified model for the lattice vibration of ferroelectric with the long-range Coulomb interaction. The real space method to investigate the lattice dynamic of the non-perfect lattice is introduced. The combined 1D chain model to simulate GaAs/SrTiO₃ system is proposed and the Raman spectrum is analyzed.
