epitaxial nucleation 中文意思是什麼

Abstract : based on the ahievement of epitaxial growth in several perovskite oxide films, we discuss the importance of substrate temperature ( ts ) and substrate material in the epitaxial growth of perovskite oxide thin films. influences of ts on growth orientation and epitaxial threshold temperature were observed. the results indicate that during the growth of the oxide films the phase formation and growth dynamics should be taken into consideration. the threshold temperature for epitaxial growth depends on the substrate materials. this demonstrates the influence of substrate material on the initial nucleation and epitaxial growth
文摘:在成功地外延生長超導、鐵電、鐵磁等多種性質的鈣鈦礦結構氧化物薄膜的基礎上，討論影響氧化物薄膜外延生長的一些因素.考慮到相形成和薄膜生長動力學，在利用脈沖激光淀積法外延生長氧化物薄膜中襯底溫度是十分重要的工藝參數.襯底溫度對成相和生長薄膜的取向都有影響.考慮到薄膜是首先在襯底表面成核、成相併生長.因此襯底材料晶格的影響是不容忽視的.觀察到襯底材料對薄膜外延生長溫度的影響.在適當的工藝條件下，利用低溫三步法工藝制備得到有很強織構的外延薄膜.這突出表明界面層的相互作用對鈣鈦礦結構薄膜的取向有著相當大的影響 -
