用电流涨落测量电子能量分布

Measuring electron energy distribution by current fluctuations

S. U. Piatrusha, V. S. Khrapai

摘要:

最近的局部噪声传感器的概念被扩展到测量能量分辨的电子能量分布$f(\varepsilon)$在一个非平衡正常金属互连内的给定位置。$f(\varepsilon)$的定量分析是复杂的,因为由扩散InAs纳米线表示的噪声传感器的非线性微分电阻。然而,通过比较非平衡结果与参考平衡测量,我们得出结论,$f(\varepsilon)$是无法区分的费米分布。

英文摘要:

A recent concept of local noise sensor is extended to measure the energy resolved electronic energy distribution $f(\varepsilon)$ at a given location inside a non-equilibrium normal metal interconnect. A quantitative analysis of $f(\varepsilon)$ is complicated because of a nonlinear differential resistance of the noise sensor, represented by a diffusive InAs nanowire. Nevertheless, by comparing the non-equilibrium results with reference equilibrium measurements, we conclude that $f(\varepsilon)$ is indistinguishable from the Fermi distribution.
