| 摘 要： | 采用购买的直径为40～50 nm的AAO模板,利用直流电沉积方法在AAO模板上制备了Cu纳米线.TEM观察发现,Cu 纳米线的直径为(45±5)nm,与AAO模板的内孔 直径一致.利用碳膜卷曲的方法,在JEOL 2010F型场发射透射电子显微镜中对单根 Cu 纳米线进行了原位弯曲变形实验.实验发现,存在于纳米线内部的孪...

| Abstract: | Cu nanowires were fabricated in commercial AAO template(diameter of the AAO template ranges from 40-50 nm) using DC electrodeposition method.TEM images show that the diameter of the nanowire is consistent with that of AAO template.Bending test of single Cu nanowire was conducted in a HRTEM using the colloidal thin film contraction method.The result shows that the twin boundary is the dislocation source emitting partial dislocations.The plastic behavior of the nanowires is mainly due to partial dislocations. |
