摘要/Abstract

摘要：

提出一个基于分子芯片, 由六个黄金电极构成的静电分束器。分束器的总长度大约10 mm。用经典的蒙特卡罗方法模拟极性分子被装载和分束的动力学过程。用此分束器, 可以得到固定的分束比为0.5:0.5。如果将两个电极杆切断, 通过改变电极电压就可以很容易地操控分束比。

关键词: 极性分子, 静电分束器, 分束比

Abstract:

A chip-based electrostatic beam splitter composed of six gold electrodes is proposed.Total length of the splitter is about 10 mm.Dynamic process of the loading and splitting polar molecules is simulated with classical Monte Carlo method.With the beam splitter, we can get a fix splitting ratio (0.5:0.5).If cutting off two pole electrodes, we can manipulate the splitting ratio conveniently with the voltage applied to the severed electrodes.

Key words: polar molecules, electrostatic beam splitter, splitting ratio
