论文摘要
我们报告了铜间隔拓扑绝缘子BI $ _2 $ SE $ _3 $混合设备中的收费和热运输研究。测得的电导率显示了量子校正，电子电子和电子 - 光子相互作用的影响。我们的射击噪声测量结果表明，随着温度的升高，热通量显示$ t^2 $和$ t^4 $之间的交叉。结果可以通过无弹性电子散射模型来解释，从而增加了横向声音子在电子偶联过程中的作用。
We report charge and heat transport studies in copper-intercalated topological insulator Bi$_2$Se$_3$ hybrid devices. Measured conductivity shows impact of quantum corrections, electron-electron and electron-phonon interactions. Our shot noise measurements reveal that heat flux displays a crossover between $T^2$ and $T^4$ with the increase of temperature. The results can be explained by a model of inelastic electron scattering on disorder, increasing the role of transverse acoustic phonons in the electron-phonon coupling process.
