TLDR

The scanning tunneling microscope has been used to image a reduced TiO(2)(110) surface in ultrahigh vacuum. Structural units with periodicities rangng from 21 to 3.4 angstroms have been clearly imaged, demonstrating that atomic resolution imaging of an ionic, wide band gap (3.2 electron volts) semiconductor is possible. The observed surface structures can be explained by a model involving ordered arrangements of two-dimensional defects known as crystallographic shear planes and indicate that the topography of nonstoichiometric oxide surfaces can be complex.read more

Resistance of a one-atom contact in the scanning tunneling microscope
TL;DR: In this paper, the resistance as a function of tip sample separation in the scanning tunneling microscope is calculated for distances in the transition region between tunneling and point contact, and good agreement is found with the recent experimental data of Gimzewski and Moller.
