层状金属中的反常c轴输运

Anomalous c-axis transport in layered metals

D. B. Gutman, D. L. Maslov

摘要:

研究了具有强各向异性单粒子谱的金属中的输运问题。在所有方向上的相干带传输,所描述的标准玻尔兹曼方程,示出承受弹性和非弹性散射只要$E_Fτ\gg 1$。声子辅助隧穿通过位于层之间的共振态的模型,建议解释在实验中观察到的c轴电阻率的非单调温度依赖性。

英文摘要:

Transport in metals with strongly anisotropic single-particle spectrum is studied. Coherent band transport in all directions, described by the standard Boltzmann equation, is shown to withstand both elastic and inelastic scattering as long as $E_Fτ\gg 1$. A model of phonon-assisted tunneling via resonant states located in between the layers is suggested to explain a non-monotonic temperature dependence of the c-axis resistivity observed in experiments.
