RuO2 nanocrystals (NCs) were deposited on carbon nanotubes (CNTs) by reactive RF magnetron sputtering using a Ru target under different conditions. Their surface morphology, structural, spectroscopic and field emission (FE) properties were studied using field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), Raman spectroscopy, and a home made high vacuum FE...
Based on diffusion-limited aggregation process, a convenient nanotechnique is demonstrated to obtain fractal silver on conductive substrate. SEM and HRTEM images show the morphology nanostructure can be well controlled by the electrochemical process. The as-fabricated silver nanostructure exhibited SERS enhancement factor approximately 105. The study can help us to combine nano-metals and nano-particles...
Regularly faceted copper (Cu) particles ranging from tens of nanometers to submicron were obtained by annealing Cu-Zr films on polyimide and single Si (100) substrates. XRD, TEM, SEM and EDS were used to characterize their microstructural properties. The results show that these particles are pure Cu element and single crystals with [111] preferred orientation. Systematical analysis demonstrates that...
