我们报告了有机导体和超导体中一个有趣的效应：单轴压缩应力诱导和/或增强超导性。单轴应力在密度波材料中诱导超导性，并使超导体的转变温度增加3倍。对舒布尼科夫-德-哈斯效应的分析表明，在诱导超导时，平面内晶胞随着应力的增加而膨胀，有效质量增加。
We report an interesting effect in organic conductors and superconductors: the inducement and/or enhancement of superconductivity by uniaxial compressive stress. Uniaxial stress induces superconductivity in a density-wave material and increases the transition temperature of a superconductor by a factor of 3. Analysis of the Shubnikov-de Haas effect shows an expansion of the in-plane unit cell with stress and an increase in effective mass when superconductivity is induced.
