Abstract
A theory is presented for the scanning vacuum-tunneling microscopy experiments performed by Binning et al. The tunnel current is obtained for different geometries and tip shapes. Lateral resolutions are 4-8 Å for distances from the tip to the sample ∼3.5-4.5 Å, effective tip radii ∼3-10 Å, 1-nA currents, and applied voltage ∼0.01 eV. The Au(110)(1×2) surface is analyzed and the experimental results discussed.Keywords
