Abstract

We report a previously unobserved superconducting state of the photosynthesized carbonaceous sulfur hydride (C-S-H) system with a maximum of 191(1) K below 100 GPa. The properties of C-S-H are dependent on carbon content, and X-ray diffraction and simulations reveal the system remains molecular-like up to 100 GPa.

摘要

我们报道了一种光合碳质硫化氢（C-S-H）体系中以前未观察到的超导态，在100吉帕以下其最高超导转变温度为191(1)K。C-S-H的性质取决于碳含量，X射线衍射和模拟表明该体系在高达100吉帕时仍保持类似分子的结构。
