| 中文摘要 | Bi2Sr2CaCu2O8+delta (2:2:1:2) single crystals are in-situ heated in a transmission electron microscope in order to investigate the structure evolution of thin foils in the vacuum. The structure becomes unstable at about 250 degrees C, and strain fields are produced along the a and b directions by the thermal expansion of the lattice; tweed contrast is formed and at about 300 degrees C twin-like deformations or precipitations occur owing to the local monoclinic lattice disorder. The deformed areas extend in the temperature range from 300 to 400 degrees C. From 400 to 450 degrees C, a new superstructure is induced presumably by the loss of oxygen or by a change of the oxygen configuration. Serious structure distortions above 400 degrees C make the lattice decompose locally. Above 460 degrees C, the 2:2:1:2 structure completely decomposes. |
