Abstract
Using the Monte Carlo techniques single steps on Kossel-type crystal surfaces were simulated under equilibrium conditions up to the temperature region where statistical theories excluding overhanging step edge (ledge) configurations are questionable. The ledge length was varied between 40 and 960 units leading to average maximal step widths up to 40 units, so reaching dimensions observable with modern electron-optical techniques. Jump and pair frequency distributions of the ledge were investigated after an equilibrium state was reached by direct tracing of its successive paths over the surface. The distributions were compared with those of an analytical low temperature step model.
