A step motor sample approach mechanism and a tripod scanner are used in the construction. Atomic resolution images of graphite samples are obtained in both constant current and constant height modes. Loss of trigonal symmetry in some Graphite images are also observed. This anomaly is attributed to the multiple atom tip or slipped top layer of Graphite.xii, 77 leaves, illustrationsEnglishinfo:eu-repo/semantics/openAccessScanning Tunneling MicroscopeTunnelingPiezoGraphiteScannerTipQC173.4.S94 O63 1990Scanning tunneling microscopy.Tunneling (Physics).Microscope and microscopy-Technique.Thesis
