我们证明了US-(BEDT-TTf)2I3(US-(C10H8S8)2I3)的高温/亚c/(8-K)超导态是由剪应力和静水压力共同作用形成的，不能单独通过存在来获得。此外，测量了常压超导体US-(BEDT-TTf)2I3、US-(BEDT-TTf)2IBr2和US-(BEDT-TTf)2AuI2的T/subc/与压力的关系，结果表明，通常的压力导数约为1K/kbar，几乎比以前报道的任何超导体的压力导数大一个数量级。我们提出了一个与这些观测结果相一致的结构模型。
We show that the high-T/sub c/ (8-K) superconducting state of US -(BEDT-TTF)2I3 (US -(C10H8S8)2 I3) is formed by a combination of shear stress and hydrostatic presure and cannot be accessed by presence alone. Also, measurements of the pressure dependence of T/sub c/ in the ambient-pressure superconductors US -(BEDT-TTF)2I3, US -(BEDT-TTF)2IBr2, and US -(BEDT-TTF)2AuI2 show a common pressure derivative of about 1 K/kbar, which is nearly an order of magnitude larger than that of any previously reported superconductor. We present a structural model which is consistent with these observations.
