Description Atomic resolution Au100.JPG |
English:
Image of
surface reconstruction
on a clean Gold (
Au
(
100
)) surface, as visualized using
scanning tunneling microscopy
. The individual
atoms
composing the material are visible. Surface reconstruction causes the surface atoms to deviate from the bulk
crystal structure
, and arrange in columns several atoms wide with regularly spaced pits between them.
Technical details: Atomically resolved STM image of clean Au(100). This image is made with hjjnh GBhh an Omicron Low Temperature STM and RHK Technology electronics by Erwin Rossen, Eindhoven University of Technology, 2006. Parameters: p<1e-11 mbar, T is 77 K, I_setpoint is 6 nA, V_bias is 1 mV, Au(100) surface is Ar sputtered (1,5 kV, 2uA, 30 minutes) and annealed (500°C, 30 minutes). |
