摘要

本文报道了在低温和超高真空环境下，扫描隧道显微镜（STM）针尖施加偏置诱导偶氮苯衍生物开关行为的可逆性和双稳定性。在+2V或-2V两种极性的STM成像过程中，在亚秒的时间尺度上观察到顺式到反式和顺式到顺式的转换。这导致在STM图像上可见的闪烁效应，对应于偶氮苯分子在施加STM偏置下通过电场诱导过程的可逆开关。

Electroisomerization blinking of an azobenzene derivative molecule.

We report here the reversibility and bistability of the switching behavior in an azobenzene derivative induced by the bias applied by a scanning-tunneling microscopy (STM) tip, at low temperature and in ultra-high vacuum environment. Thiscis-to-transandtrans-to-cisswitching were observed during STM imaging in either polarity at +2 V or -2 V, on a sub-second time scale. This results in a blinking effect visible on STM images, corresponding to the reversible switching of the azobenzene molecule under the applied STM bias through an electric field induced process.

期刊介绍： The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
