| Abstract: | In this paper, a method of fabricating STM tips was reported. Moreover, according to the principle of freely falling body, a new electrochemical device for separating the tip and the solution during fabricating STM tips was constructed. In addition the comparison with the tip lift method using the step motor was made. The experiments and the analysis show that the method is simple and economical, it has the higher separating speed and gives good results. |
