Abstract:
Double-walled Metal Nanotubes (DWMNTs) were fabricated by using the system of rotational depositing. The porous anodic aluminum oxide (AAO) templates were prepared by using aluminum (99.999%) foils and anodizing them by the oxalic acid (C2H2O4) 0.3 M electrolyte and the pores of AAO templates were widened by phosphoric acid (H3PO4) 0.5 M at the temperature of 30°C (pore-widening proses). After pore-widening, Au and Cu were deposited by the method of electron-beam deposition in the form of layer by layer inside AAO templates by the system of rotational deposition at the specific angle (45°) respectively. In addition, the double-walled metal nanotubes (DWMNTs) were indicated by TEM micrographs and EDX spectra. This method can be applied in engineering applications, for example, for the fabrication of nano-capacitors or for increasing the number of nanotubes per unit area, that this factor will increase the efficiency of solar cells and also it can be used in sensors and other applications.
