我们提出了用于电化学蚀刻的控制电路，可重复尖锐的STM探针。该设计使用Arduino UNO微控制器，允许交流和直流操作，以及一个比较器驱动的关断，允许在0.5-1 μ s内停止蚀刻。Arduino允许仪器定制，以适应各种潜在的应用，而无需对硬件进行重大更改。数据提出了粗化学蚀刻80:20铂铱，钨和镍尖端。(C) 2012年美国物理研究所。[http://dx.doi.org/10.1063/1.3695001]
We present control circuits designed for electrochemically etching, reproducibly sharp STM probes. The design uses an Arduino UNO microcontroller to allow for both ac and dc operation, as well as a comparator driven shut-off that allows for etching to be stopped in 0.5-1 mu s. The Arduino allows the instrument to be customized to suit a wide variety of potential applications without significant changes to hardware. Data is presented for coarse chemical etching of 80:20 platinum-iridium, tungsten, and nickel tips. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.3695001]
