论文摘要
高t $ _c $材料的室温热扩散率由声子主导。这使电子通过电子散射的散射能够辨别。我们认为，这种散射的测得的强度表明，声子在这些材料的室温相图上通过声子进行了匡威普朗克散射。与这一结论一致，强烈过度挤压物的电阻率的温度导数表明在低于200 K的扭结中，我们认为应该将其理解为电子电子对电子的高温planckian $ t $线性散射的发作。这种扭结不断消失在最佳掺杂方面，即使电子对声子的强烈散射在热扩散率中仍然可见，从而锐化了与声子散射发作相关的$ t $ linear电阻率中缺乏特征的长期难题。
The room temperature thermal diffusivity of high T$_c$ materials is dominated by phonons. This allows the scattering of phonons by electrons to be discerned. We argue that the measured strength of this scattering suggests a converse Planckian scattering of electrons by phonons across the room temperature phase diagram of these materials. Consistent with this conclusion, the temperature derivative of the resistivity of strongly overdoped cuprates is noted to show a kink at a little below 200 K that we argue should be understood as the onset of a high temperature Planckian $T$-linear scattering of electrons by classical phonons. This kink continuously disappears towards optimal doping, even while strong scattering of phonons by electrons remains visible in the thermal diffusivity, sharpening the long-standing puzzle of the lack of a feature in the $T$-linear resistivity at optimal doping associated to onset of phonon scattering.
