摘要：

An ECSTM apparatus with an ideal tip using a homemade SSX-1A STM instrument has been constructed. STM and ECSTM tips were made by electrochemical etching and insulating with paraffin, silicon rubber or epoxy resin under an optical microscope. In situ imaging of highly oriented pyrolytic graphite (HOPG) shows that the leakage current passing through the tip has been effectively eliminated. By this technique we have studied the growth and mechanism of polypyrrole films on HOPG. Using the STM technique we have also studied a metalloporphyrin compound, FAD and tungstosilicic acid modified on HOPG.
