Peierls-Like Distortion in Yttrium Trihydrides 来自 ResearchGate 喜欢 0 阅读量: 47 作者: MY Chou 展开 摘要: We have carried out first-principles total-energy calculations for yttrium trihydride(Y. Wang and M. Y. Chou, Phys. Rev. Lett. 71), 1226 (1993); Phys. Rev. B 51, ...
Spin-PeierlsWe investigate the role of the spin–lattice coupling in the antiferromagnetic molecular rings and the possible appearance of a dimerized phase. We argue that the Cu 8 might be a good candidate to observe such a phase.doi:10.1016/j.jmmm.2003.12.633L. Spanu...
We suggest that the lattice distortion caused by the Li-doping is responsible for the enhancement of the phase transition. 机译:在尖晶石CuIr_2S_4系统中,以前的报告表明,任何化学取代都会抑制或破坏Peierls样的相变。在这里,我们介绍我们对Cu _(1-x)Li_xIr_2S_4系统的研究,其中通过掺杂Li增强了...

The mechanism that leads to the mode softening is reminiscent of the driving force inducing Peierls distortions, but the energy gained by opening the gap is not sufficient for a static lattice distortion. Instead, the corresponding vibrational frequency is lowered. 展开 关键词: Carbon nanotubes ...
In all cases, the periodic lattice distortion can be associated to a 2kF Peierls instability of the perylene chains. The Ni compound shows in addition to the 2kF distortion also a lattice instability at twice this wave vector, which corresponds to a dimerization of the Ni(mnt)2 chain of ...
