Abstract: The STM observations of growth spirals in bulk single crystals of Y-123 and Bi-2122 high Tc cuprates are reported for the first time. The density of screw dislocations present is of the same order as recently reported for sputtered epitaxial thin films of Y-123. Growth features are briefly discussed and it is argued that the observed dislocation density is still too low for realizing optimum flux pinning in these HTSC systems.
