Abstract: We study atomic steps on surfaces of
crystals. the crystals under consideration are called ``unorthodox''
since their atomic steps show increasing oscillations for decreasing
temperatures. Using a physical model for the shape of atomic steps on
the surface of these crystals we perform numerical simulations for
terrace- and island-like shapes of atomic steps. Moreover we use the
-limit approximation of the model to compare its solutions
with experimental data and derive information on the temperature
depenence of the relevant physical constants. this method may prove
useful also in other physical problems th multiple scales.
