论文摘要
我们报告了PseudoGap相位能量表的孔掺杂依赖性,$2δ_ {\ rm Pg} $,抗Nodal(Nodal)超导能量尺度$2Δ^^an} _ {\ rm Sc} $2Δ^{\ rm sc} $ $2δ_ {\ rm cdw} $。它们是从不同氧化铜家族的电子拉曼反应中提取的。对于所有研究的丘陵,我们揭示了普遍的兴奋剂依赖性,这表明$2δ_ {\ rm pg} $,$2δ^{an} _ {\ rm sc} $和$2δ_{\ rm cdw} $由常见的微观互动和这些相关的交易$ yeptive ye the Sperccomdivectimant ye Sperccording the Suppercondive the Suppercomdive the Supperconding。相比之下,$2δ^n _ {\ rm sc} $跟踪$ t_c $的掺杂依赖性,似乎由与上面的能量尺度不同的相互作用控制。
We report the hole doping dependencies of the pseudogap phase energy scale, $2Δ_{\rm PG}$, the anti-nodal (nodal) superconducting energy scales $2Δ^{AN}_{\rm SC}$ ($2Δ^{N}_{\rm SC}$) and the charge density wave energy scale, $2Δ_{\rm CDW}$. They have been extracted from the electronic Raman responses of distinct copper oxide families. For all the cuprates studied, we reveal universal doping dependencies which suggest that $2Δ_{\rm PG}$, $2Δ^{AN}_{\rm SC}$ and $2Δ_{\rm CDW}$ are governed by common microscopic interactions and that these interactions become relevant well above the superconducting transition at $T_c$. In sharp contrast, $2Δ^N_{\rm SC}$ tracks the doping dependence of $T_c$, appearing to be controlled by a different kind of interactions than the energy scales above.
