Abstract

Transmission electron microscopy was used to investigate defect microstructures in single crystals of YBa₂Cu₃O_7-δ as a function of ion irradiation dose at 300 K. Two qualitatively different defect microstructures were observed to precede amorphization. The transition between microstructures occurs at a damage level where published resistance versus temperature measurements indicate a transition from superconducting to insulating behavior.

3. RESULTS AND DISCUSSION Selected electron micrographs from one irradiation are displayed in Fig. 1. A continuous buildup in density of small defects ( 5 nm black-white or black spot contrast features) was observed in exactly the same sample area through a dose of 3.5x1014 Ne + cm -2 (Fig. lc). Also, through this dose, no change in diffraction patterns was observed. However, at higher doses (Fig. ld and f) the onset of a partially amorphous structure was observed as a faint ring *Work supported by the U.S.Department of Energy, Basic Energy Sciences--Materials Science under contract #W-31-109-Eng-38 (MAK, JZL, LJT, JRW, EAR, STO) and the National Science Foundation--Office of Science and Technology Centers under contract #STC-8809854 (MCF).
