面缺陷是纳米带中非常普遍和非常重要的一类缺陷。在有些情况下,面缺陷对于高表面能指数面的出现起着决定性的作用,同时,它们可以诱导纳米带沿着特殊的方向生长。面缺陷可以是孪晶或双晶,层错和由杂质原子聚集在特定原子面所形成的间隙原子层。在本文中,利用透射电子显微术,我们将介绍氧化锌纳米带中被发现的几种面缺陷。我们确认了两种孪晶/双晶结构,它们的孪晶面分别是(0113)和(2112)面。基面层错有I1和I2两种。在大尺寸的纳米带中,I1基面层错可以折叠到(2110)面形成棱面层错。当少量的In离子掺入氧化锌纳米带后,我们发现伴随着杂质In在基面的聚集,形成了两种倒反畴界。
Surface defects are a very common and very important type of defect in nanoribbons. In some cases, surface defects play a decisive role in the appearance of high surface energy index surfaces, and at the same time, they induce the nanoribbons to grow in specific directions. Surface defects can be twins or bilayers, stacking faults and interstitial atomic layers formed by agglomeration of impurity atoms at specific atomic planes. In this paper, using transmission electron microscopy, we describe several surface defects found in zinc oxide nanoribbons. We confirmed two twin / twin structures with twin planes of (0113) and (2112), respectively. The basal plane fault I1 and I2 two. In the large size of the nanoribbons, the I1 basal plane faults can be folded into (2110) planes to form facet faults. When a small amount of In ions are doped into the ZnO nanoribbons, we find that there are two kinds of inversion domains formed along with the accumulation of impurity In.
