中文摘要
本论文主要研究了具有巨c/a比的BiFeO_3晶体。第一性原理计算表明,BiFeO_3晶体具有~150 μC/cm ~ 2的巨反射极化,因此引起了人们的广泛关注。制备了菱形BFO、巨型c/aBFO及其混合相薄膜。在SrRuO_3/SrTiO_3衬底上可以得到巨大的c/a BFO,TEM观察到800畴。在LaAlO_3(001)衬底上制备了高质量的c/aBFO巨膜,并证实了其光伏效应。
英文摘要
In this study, we focused on BiFeO_3with giant c/a ratio which is attracted much attention because of its giant remanent polarization of ~150 μC/cm2predicted by first-principles calculation. Rhombohedral BFO, giant c/aBFO and their mixed phase thin films have been prepared. The giant c/a BFO can be obtained on SrRuO_3/SrTiO_3substrate, and 80odomain can be observed by TEM. The high quality giant c/aBFO films can be obtained on LaAlO_3(001) substrate, and photovoltaic effect have been confirmed.
