Manipulation of Au nanoparticles using an electron probe: electron golf
摘要：
一种用于操纵特定纳米颗粒的工具对于纳米纤维是必不可少的。本文描述了一类新的纳米技术，用于使用聚焦电子束操纵绝缘基底上的单个纳米颗粒。20 nm金纳米粒子的控制位移证明，随着扩展到其他系统，通过利用粒子运动的基本原理，在强烈的电子照射下，我们阐明。在这种新的机制中，通过衬底内的聚焦电子束的激发和电离示出在颗粒上产生电场。电场的强度和方向以及纳米颗粒的运动可以通过电流密度、暴露时间和电子束的位置来精确控制。
英文摘要：
A tool for manipulation of specific nanoparticles is essential for nanofabrication. This paper describes a new class of nanoscale techniques for manipulating individual nanoparticles on an insulating substrate using a focused electron beam. The controlled displacement of 20 nm Au nanoparticles is demonstrated, along with the extension to other systems, by exploiting the fundamental principles of particle motion under intense electron irradiation, which we elucidate. Excitation and ionization by the focused electron beam within the substrate are shown to produce an electric field on the particle in this new mechanism. The strength and direction of the electric field, and thus the motion of the nanoparticle, can be precisely controlled by the current density, exposure time and position of the electron beam.
