Data underlying the publication: Mechanically Stable Kondo Resonance in an Organic Radical Molecular Junction

Data and scripts used in the publication: Mechanically Stable Kondo Resonance in Organic Molecular Junctions. An MCBJ setup was used to measure two organic radical molecules with different substitutions of the central benzene ring of the molecular backbone at both room- and low-temperature. The goal was to investigate the impact of quantum interference in the backbone on spin-related phenomena. At room-temperature, large sets of breaking traces were collected at a constant bias voltage and histograms were constructed. At low-temperature, current-voltage characteristics were recorded while increasing the electrode separation. We find that the configuration of the molecular backbone affects the coupling of the radical to the electrode.

本研究发表所用的数据与脚本来自论文《有机分子结中机械稳定的近藤共振（Kondo Resonance）》。本工作采用机械可控劈裂结（MCBJ）实验装置，分别在室温和低温条件下，对两类分子主链中心苯环带有不同取代基的有机自由基分子开展表征测量。本研究旨在探究分子主链中的量子干涉效应对自旋相关物理现象的影响。在室温环境下，实验采集了大量恒定偏置电压下的断裂电导轨迹，并据此构建了电导直方图；在低温环境下，实验记录了电极间距逐渐增大过程中的电流-电压特性曲线。研究结果表明，分子主链的构型会影响自由基与电极之间的电子耦合强度。
