Plasma enhanced chemical vapor deposition of palladium in anodic aluminum oxide template

Owning to the robust characteristics of diamonds, a nano-tip array structured mold was fabricated with diamond, we can then use this mold to produce anti-reflection (AR) films with nanoimprint lithography. Taking advantage of the self-ordered characteristic of anodic aluminum oxide (AAO), we can obtain the diamond mold by depositing a layer of diamond on the AAO using hot filament chemical vapor deposition (HFCVD). Then taking advantage of the high through-put characteristics of nanoimprint lithography, AR films can be mass produced. The AR films were subjected to reflectivity inspections, a 5.5% reduction in reflectivity was obtained.

Anodic Aluminum

Carbon nanotube (CNT) is one of the most attractive materials for the potential applications of nanotechnology due to its excellent mechanical, thermal, electrical and optical properties. We demonstrated the fabrication of carbon nanotube and carbon nanofiber (CNF) inside the pore and at the surface of anodic aluminum oxide (AAO) membrane by chemical vapor deposition method at atmospheric pressure. Ethanol was used as a hydrocarbon source and Co–Mo as catalyst. CNT was synthesized at different temperature. High graphitic multiwall carbon nanotube (MWCNT) was found at 750°C, while CNF was found at 800°C and above temperature analyzing by Raman spectroscopy.

Controllable Size

Carbon spheres were synthesized by chemical vapor deposition. The products deposited at different zones were separately collected. Furthermore, an anodic aluminum oxide template was used to control the size of carbon spheres. The products were characterized by field-emission scanning electron microscopy, high resolution transmission electron microscopy and X-ray diffraction. The results show that carbon spheres with controllable size distribution were obtained and the size distribution of these carbon spheres can be controlled to some degree by deposition zone and anodic aluminum oxide template.

Potential Applications

Carbon nanotube (CNT) is one of the most attractive nanomaterials which may be used in many potential applications of nanotechnology due to its excellent mechanical, electrical and thermal properties. We demonstrated the fabrication of carbon nanotube at the surface of anodic aluminum oxide (AAO) membrane by chemical vapor deposition (CVD) method. Acetylene was used as a hydrocarbon source and Fe as catalyst. CNT was synthesized at different temperature. The iron catalyst was confined in the holes of the AAO membrane. A variety of carbon structures such as nanotubes, helices, spiral, and hook-like curved shapes in the range of micrometer were synthesized. High graphitic multiwall carbon nanotube (MWCNT) was found at 700-750°C temperature.
