See larger version of surface image above and a image created with Vistapro.
Ag(111) surface imaged at 120 Kelvin.
The size of the image is 1600 angstroms x 1600 angstroms. The triangular shape is due to the thermal contraction of two different layers, Si(111) as substrate and Ag(111). These straight lines correspond to some unique crystallographic orientation. You are looking at a topographic view. Each step has vertical height of 2.5 angstroms. Individual atoms are not resolved due to the sea of electrons characteristic of a metal. The RAW data file is 1000 angstroms on a side.
Vistapro surface file: 7001Ag.DEM
