新型二维蜂窝层状Cu3LiRu2O6具有Pauli类顺磁和Mott变程跳跃的超导行为，与金属的大比热Sommerfeld系数相矛盾，表明可能是自旋激发诱导的非金属材料.这种非金属的功能可以显着抑制压力对生产不良金属状态，反映了温度依赖性电阻率响应高达35 GPa。
The novel two-dimensional honeycomb layered Cu3LiRu2O6 exhibits Pauli-like paramagnetic and Mott variable range hopping semiconduction behaviors, which contradict the large specific-heat Sommerfeld coefficient for metals, and indicate a possible spin-excitation induced nonmetallic metal. This nonmetallic feature can be significantly suppressed by pressure toward producing a bad-metal state, as reflected by the temperature-dependent resistivity response up to 35 GPa.
