It was recalled that screw dislocations were step sources which permitted crystals to grow under low driving forces. Growth was accelerated at the out-crop of a screw dislocation, which generated a spiral hillock. The interaction between dislocation growth, 2-dimensional nucleation and misorientation step-flow was investigated here, for a wide range of driving forces, by means of Monte Carlo simulations of the growth of the Kossel (100) surface. The interactions between various growth mechanisms were shown to agree with a general model, for velocity-source behavior, which permitted a simple analytical expression of the growth rate. This expression could be used in a continuum description of crystal growth. Dislocation etching was also compared with dislocation growth.
