不对称掺杂聚乙炔
Asymmetrically Doped Polyacetylene
摘要：
掺杂的一维（1D）共轭聚合物，如聚乙炔，具有某些金属的导电性，如铜。我们表明，当这种聚合物是不对称掺杂，意想不到的性能被揭示，相比的对称标准掺杂系统（SDS）的行为。根据两个所涉及的费米子物种的化学势之间的不平衡水平，聚合物可以转化为1D部分或完全自旋极化的有机导体。
英文摘要：
Doped one-dimensional (1D) conjugated polymers, such as polyacetylene, have a conductivity of some metals, like copper. We show that when this polymer is asymmetrically doped, unexpected properties are revealed, when compared to the behavior of the symmetrically standard doped systems (SDS). Depending on the level of imbalance between the chemical potentials of the two involved fermionic species, the polymer can be converted into a 1D partially or fully spin polarized organic conductor.
