The I-V curve of the plasma in gas discharge is measured using dual probe method,and an asymmetry of I-V curve is observed.
利用气体放电双探针法研究了等离子体的I-V曲线中的电流I相对于电压V轴交点的不对称性,并提出2种可能的解释:一认为是由于两探针表面积不同引起的;二认为是由于探针所在处等离子体电位不等引起的。
First, a double-tip STM was constructed based on a specially designed electric control system, and a method for double tip aligned was suggested.
首先,设计了适于双探针的电子控制系统,构筑了一套双探针STM,利用双探针STM实现了双钨针尖的对准,并测定了对准后的双钨针尖构成的纳米结构的I—Z曲线和I—V曲线。
