摘要：

The defect structure of superconducting single crystal whiskers BSCCO (2212) was studied by high voltage transmission electron microscopy. Dislocations, twins, growth steps, antiphase domains associated with a commensurate modulation and antiphase boundaries of incommensurate modulation were found. The latter are inherent to all whiskers in contrast to any other defects. The defect structures of the whiskers and BSCCO (2212) plate-like single crystals are compared. The influence of some defects on superconducting properties of the material is discussed. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
