Аннотация:The atomic-force microscopy method is used to study the structure of the surface and the formation of a dislocation spiral on the (010) face of a potassium hydrogen phthalate crystal grown from a water-alcohol solution. It is shown that the face grows according to the dislocation mechanism. Channels surrounding dislocation sources with a large Burgers vector are discovered. The density of kinks at the steps was so high that no smooth regions were observed between kinks. The velocity of a step fluctuates, with the fluctuations growing in proportion to the fourth root of time. During the formation of a spiral, a segment of a step acquires a constant velocity independent of its length after attainment of the critical length. (C) 2003 MAIK "Nauka / Interperiodica".
