  • Received Date: 2014-10-09
  • We demonstrate a home-built electrochemical scanning tunneling microscope (ECSTM). The ECSTM exhibits highly stable performance. The drifting rates in XY and Z directions of the ECSTM are about 67 and 55.6 pm/min, respectively. Moreover, a specially designed scanner unit successfully solves the well-known problem of large leakage current in high humidity atmosphere. The mechanical structure of the ECSTM is described in detail. The excellent performances of the system are demonstrated by the measured STM images (in copper sulfate solution), including clean and well-ordered large area morphology of Au(111) and the atomically resolved image of highly oriented pyrolytic graphite.

A Highly Stable Electrochemical Scanning Tunneling Microscope

Abstract: We demonstrate a home-built electrochemical scanning tunneling microscope (ECSTM). The ECSTM exhibits highly stable performance. The drifting rates in XY and Z directions of the ECSTM are about 67 and 55.6 pm/min, respectively. Moreover, a specially designed scanner unit successfully solves the well-known problem of large leakage current in high humidity atmosphere. The mechanical structure of the ECSTM is described in detail. The excellent performances of the system are demonstrated by the measured STM images (in copper sulfate solution), including clean and well-ordered large area morphology of Au(111) and the atomically resolved image of highly oriented pyrolytic graphite.
