Abstract
The oscillation part of the effective indirect inter-action between potassium adatoms adsorbed on (112) plane of tungsten was used to simulate the dynamics of adsorbed atoms. Simulations of field emission flicker noise have been done using a standard Monte Carlo method. A lattice used in simulation was 18x29. For three positions of the collector the mean square fluctuations have been computed. Results are in qualitative agreement with the experiment. A c(2x2) structure is created for the low temperature limit.
