First-principles molecular dynamics study of a polymer under tensile stress

The Journal of Chemical Physics, 2001
We present first-principles simulations of cis-polyacetylene fragments under tensile stress. The barrier of a cis-trans isomerization of conjugated carbon–carbon double bonds is lowered by tensile stress. However, it does not seem likely that the barrier can be sufficiently reduced to achieve a cis-trans isomerization in an atomic force microscopy ...

First principles study of the responses to equibiaxial in-plane tensile stresses in tetragonal BaTiO3

Journal of Alloys and Compounds, 2010
Abstract Tetragonal BaTiO 3 under equibiaxial in-plane tensile stresses is investigated from first principles calculations. Our results show that this material transfers to the paraelectric phase at the critical stress of about 13 GPa. We also find the great enhancement of piezoelectricity close to the phase-transition region, due to large atomic ...
