本研究采用电子通道技术（ＥＣＰ）对单晶和双晶外延生长的ＹＢａ＿２Ｃｕ＿３Ｏ＿７（ＹＢＣＯ）超导薄膜的结构、取向和表面完好性作检测，并证实对衬底的预处理可改善外延超导薄膜的质量；还对ＹＢＣＯ／ＣｅＯ＿２／ＭｇＯ／ＳｒＴｉＯ３的双外延薄膜作研究。
In this study, the structure, orientation and surface integrity of YBa 2 Cu 3 O 7 (YBCO) thin films grown by single-crystal and twin-crystal epitaxial growth were examined by electronic channeling (ECP). The results show that pretreatment of the substrate can improve the epitaxial superconducting thin films The mass of YBCO / CeO 2 / MgO / SrTiO 3 double epitaxial films was also investigated.
