In addition, theoretical analysis indicates that the reduction in the lattice thermal conductivity with vacancy defects can be explained by the enhanced point-defect scattering due to lattice strain.
A bipolaron microscopic model is proposed in this paper to interpret theoretically the Raman scattering data in cis-polyacetylene on the basis of lattice relaxation theory.
