| 1 | Promising electroplating solution for facile fabrication of Cu quantum point contacts显示文摘在这篇文章,我们在制造和一个新奇、电气化学地帮助的机械地可控制的裂缝连接(EC-MCBJ ) 准备的 Cu 量点接触的运输大小上报导方法。由采用影印石版术和湿蚀刻的过程,推迟了电极对在 Si 微芯片上成功地有图案、制作。而非采用一个酸 Cu electroplating 答案,一个新奇碱的 electroplating 答案被开发并且利用了建立在电极对之间的 Cu nanocontacts。典型地,同样制作的 Cu nanocontacts 的宽度被发现比 18 nm 小。很多 Cu 量点接触然后被造家的 MCBJ 安装生产并且描绘。除了常规直方图,在山峰趋于与增加传导力在振幅减少的地方,传导力直方图的一种异常类型,展出不同山峰振幅,被观察。通过最大值的统计分析 Si 微芯片,和理论计算的许可的弯曲,我们证明我们的碱的 Cu electroplating 答案负担得起与随后的 MCBJ 操作兼容的 Cu nanocontacts,它为 Cu 量点接触的制造是必要的。当复杂电子横梁平版印刷术没被要求, EC-MCBJ 方法快、简单、划算。而且,它是可能的对从他们的各自的 electroplating 答案的各种各样的金属的量点接触的制造和描述合适。 | Yang Yang Junyang Liu Jueting Zheng Miao Lu Jia Shi Wenjing Hong Fangzu Yang Zhongqun Tian | 2017 | Nano Research2017，10，10： | 2 |
| 2 | Quantum interference effect in the charge transport through single-molecule benzene dithiol junction at room temperature:An experimental investigation显示文摘The quantum interference effect in the charge transport through single-phenyl molecules received intensive interests from theory but remained as an experimental challenge. In this paper, we investigated the charge transport through single-molecule benzene dithiol(BDT) junction with different connectivities using mechanically controllable break junction(MCBJ) technique. By further improving the mechanical stability and the electronic measuring component of the MCBJ set-up, we obtained the conductance histograms of BDT molecules(BDTs) from the statistical analysis of conductance-distance traces without data selection. By tuning the connectivity, the conductance of BDTs is determined to be 10^(-1.2)G_0, 10^(-2.2) G_0 and 10^(-1.0)G_0 for para, meta, and ortho connectivity, following the trend that ortho-BDT >para-BDT >meta-BDT. Furthermore, the displacements of the junctions followed the trend that para > meta > ortho, suggesting the charge transport through the molecules via the gold-thiol bond.The different trends between conductance and displacement for different connectivities suggests the presence of destructive quantum interference effect on meta-BDT, which provides the experimental evidence for the quantum interference effect through single-phenyl molecular junctions. | Guogang Yang Hao Wu Junying Wei Jueting Zheng Zhaobin Chen Junyang Liu Jia Shi Yang Yang Wenjing Hong | 2018 | Chinese Chemical Letters2018，29，1： | 2 |

| 7 | Halide Anchors for Single-Cluster Electronics显示文摘Due to their unique electronic structure,well-defined metal clusters at the atomic level are promising materials for single-cluster electronics.However,coupling between the electrode and the cluster remains challenging mainly due to the coverage of bulky ligands on the noble clusters.Using the scanning tunneling microscopy break junction(STM-BJ)technique,we have developed a“direct contact”approach to fabrication and investigation of the charge transport through single-cluster junctions of AgCu bimetallic metal clusterswith different halide anchors.Wefound that the electrodes could make contact directly with the surface halides of the single-cluster junctions and experience different contact resistance from different halogen atoms.Experiments and calculations reveal that the halide anchors provided efficient coupling between the cluster and the electrode,and the enhanced coupling with various halide anchors promoted electron transport and improved transmission probability.Our work offers a“direct contact”strategy for interface design between clusters of noble metals and electrodes,an essential step in progress toward single-cluster electronics. | Caiyun Wei Jingyao Ye Yuming Su Jueting Zheng Siqiang Xiao Jiawei Chen Saisai Yuan Chengyang Zhang Jie Bai Han Xu Jia Shi Jiale Huang Wenjing Hong | 2023 | CCS Chemistry2023，5，7： | 0 |
| 8 | Structure Identification for Force-Induced Reaction Using Single-Molecule Conductance Measurement显示文摘Spiropyran derivatives are prototype mechanophores with a promising application as molecular sensors because of their changeable structure under external force stimuli.However,the chemical structure evolution under external stimuli remains unclear due to the uncertainty and difficulty in distinguishing the structures of different ring-opened merocyanine isomers generated in the force-induced reaction.Here we identify the structure of isomers produced by the force-induced reaction of spiropyran derivatives using a single-molecule conductance measurement and an unsupervised clustering algorithm.We found that the original data from the single-molecule conductance measurement can be divided into four clusters through unsupervised clustering.By introducing a photoinduced reaction and theoretical calculation,we identified and attributed the four clusters of data to the multiple states of the molecular junctions.Our work demonstrates that a single-molecule break junction measurement can distinguish the isomers in the force-induced reaction,suggesting the great potential of single-molecule conductance measurement and unsupervised clustering approaches for structural analysis. | Jueting Zheng Wenli Gao Taige Lu Lijue Chen Luchun Lin Ruiyun Huang Yongxiang Tang Gang Dong Junyang Liu Yifei Pan Wengui Weng Wenjing Hong | 2023 | CCS Chemistry2023，5，8： | 0 |
| 9 | Intermolecular coupling enhanced thermopower in single-molecule diketopyrrolopyrrole junctions显示文摘Sorting out organic molecules with high thermopower is essential for understanding molecular thermoelectrics.The intermolecular coupling offers a unique chance to enhance the thermopower by tuning the bandgap structure of molecular devices,but the investigation of intermolecular coupling in bulk materials remains challenging.Herein,we investigated the thermopower of diketopyrrolopyrrole(DPP)cored single-molecule junctions with different coupling strengths by varying the packing density of the self-assembled monolayers(SAM)using a customized scanning tunneling microscope break junction(STM-BJ)technique.We found that the thermopower of DPP molecules could be enhanced up to one order of magnitude with increasing packing density,suggesting that the thermopower increases with larger neighboring intermolecular interactions.The combined density functional theory(DFT)calculations revealed that the closely-packed configuration brings stronger intermolecular coupling and then reduces the highest occupied molecular orbital(HOMO)-lowest unoccupied molecular orbital(LUMO)gap,leading to an enhanced thermopower.Our findings offer a new strategy for developing organic thermoelectric devices with high thermopower. | Chao Fang Renad Almughathawi Qingqing Wu Wenqiang Cao Hang Chen Songjun Hou Yu Gu Hewei Zhang Yi Zhao Jueting Zheng Guopeng Li Jia Shi Junyang Liu Bing-Wei Mao Zitong Liu Colin J.Lambert Wenjing Hong | 2023 | National Science Open2023，2，1： | 0 |
| 10 | The fabrication,characterization and functionalization in molecular electronics显示文摘Developments in advanced manufacturing have promoted the miniaturization of semiconductor electronic devices to a near-atomic scale,which continuously follows the‘top-down’construction method.However,huge challenges have been encountered with the exponentially increased cost and inevitably prominent quantum effects.Molecular electronics is a highly interdisciplinary subject that studies the quantum behavior of electrons tunneling in molecules.It aims to assemble electronic devices in a‘bottom-up’manner on this scale through a single molecule,thereby shedding light on the future design of logic circuits with new operating principles.The core technologies in this field are based on the rapid development of precise fabrication at a molecular scale,regulation at a quantum scale,and related applications of the basic electronic component of the‘electrode-molecule-electrode junction’.Therefore,the quantum charge transport properties of the molecule can be controlled to pave the way for the bottom-up construction of single-molecule devices.The review firstly focuses on the collection and classification of the construction methods for molecular junctions.Thereafter,various characterization and regulation methods for molecular junctions are discussed,followed by the properties based on tunneling theory at the quantum scale of the corresponding molecular electronic devices.Finally,a summary and perspective are given to discuss further challenges and opportunities for the future design of electronic devices. | Yi Zhao Wenqing Liu Jiaoyang Zhao Yasi Wang Jueting Zheng Junyang Liu Wenjing Hong Zhong-Qun Tian | 2022 | International Journal of Extreme Manufacturing2022，4，2： | 0 |
