| Popis: | A miniaturized scanning tunneling microscope (STM) was put in a UHV electron microscope to simultaneously observe specimen surfaces in transmission electron microscope images and STM images. Gold (111) stepped surfaces were observed with a gold STM tip with a spherical apex curvature of 16 nm. The tip positions were measured from the electron microscope images recorded on a VTR during the STM observation. We found that the tip position changed coincidentally with the STM profile and that the shortest distance between the stepped (111) surface of the island and the spherical tip apex was kept constant. |
