概要
- 論文の詳細を見る
Radiation damage of the YBa_2Cu_4O_y (124) superconductor induced by a 1 MV electron beam is examined by ultra high-resolution high-voltage electron microscopy. Small spots with nearly amorphous structure are formed mainly at the (CuO)_2 double-chain layers at an early stage of irradiation, and their area gradually increases with irradiation time. It is considered that the amorphization is induced by direct knock-on displacements of atoms by collisions with a high-energy electron beam.
