超导NCCO的各向异性电导率

Anisotropic conductivity in superconducting NCCO

U. Michelucci, A. P. Kampf, A. Pimenov

摘要:

电子掺杂的铜氧化物如NCCO的面内和c轴电导率的低温行为进行检查,它被证明是一致的各向同性准粒子散射率和各向异性层间跳跃参数,这是非零的平面动量沿d $_{x^2-y^2}$序参量节点的方向。基于这些假设,我们发现,在平面和c轴电导率,随温度呈线性变化,在毫米波频率与实验数据一致。

英文摘要:

The low temperature behaviour of the in-plane and c-axis conductivity of electron-doped cuprates like NCCO is examined; it is shown to be consistent with an isotropic quasiparticle scattering rate and an anisotropic interlayer hopping parameter which is non-zero for planar momenta along the direction of the d$_{x^2-y^2}$ order parameter nodes. Based on these hypotheses we find that both, the in-plane and the c-axis conductivity, vary linearly with temperature, in agreement with experimental data at millimiter-wave frequencies.
