The 2D heterogeneous nucleation assisted by the defects and the successive stages of layer-by-layer growth of a fcc(111) surface on which emerged the outcrops of a dipole of screw dislocation, a piece of stacking fault [1], an A-Type twin lamella (re-entrant corner growth)[2,3], and a B-type twin lamella (rough stripe growth ) [4,5] have been studied in an unified manner [6]. The influences of supersaturation, bond energy, growth temperature and characteristic parameters of the defects upon the growth kinetics and surface morphology for different defect mechanisms have been compared [7].
