| 摘 要： | 通过自行设计控制电路,采用2种电化学方法制备了溶液中稳定的原子尺度银量子线,并进行了电学表征.第1种方法是直接电化学腐蚀/沉积法,通过仔细控制电化学腐蚀/沉积过程,观察到了台阶式的电导变化过程.第2种方法是电化学定向沉积法,与前一种方法比较,更加简单,干扰少,更适合对量子线原位进行研究.所制得的Ag量子线的I-U曲线在...

| Abstract: | Stable Ag quantum wire with atomic-scale was successfully fabricated and electrically characterized with two kinds of electrochemical method in solution by a home-made electrochemically controlled system.The first method was directly electrochemical etching and depositon.By careful controlling the etching/deposition process,stepwise conductance behavior could be clearly observed.The second method was electrochemically directional electrodeposition.Compared with the first method,the sencond one was more simple,less interferential and more suitable for in-situ study of quantum wire.The I-U curve of the formed Ag quantum wire showed the ohmic behavior with low bias voltage and electromigration phenomenon with higher bias voltage.The work is of great significance for molecular electronics,interface electrochemistry and sensing. |
