WebbHowever, for Fig. 5 (c), the ZnO nanowires are first grown and then followed by annealing, yielding an excellent ZnO nanowires packaging result as shown in the SEM image Fig. 5 (c). For Fig. 5 (d), as annealing is conducted before the hydrothermal growth of ZnO nanowires, the ZnO nanowires packaging therefore is not as good as that in Fig. 5 (c). WebbNanowires can be made from a wide variety of materials, including silicon, germanium, carbon, and various conductive metals, such as gold and copper. Their small size makes them good conductors, with electrons passing easily through them, a property that has allowed for important advances in computer science.

WebbIn order to fully understand the plasticity in nanowires, a large number of parameters are varied as part of this study. The orientations of the nanowires studied are three high symmetry directions, /100S, /110S and /111S. Three diameters, 5, 7.5, and 10nm, are used. The orientation and size of the nanowires are thought to provide the largest ...
