摘要：

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.
