Optical properties of ordered carbon nanotube arrays grown in porous anodic alumina templates.
We have synthesized ordered carbon nanotube (CNT) arrays in porous anodic alumina (PAA) matrix, and have characterized their total optical reflectance and bi-directional reflectance distribution function after each processing step of the microwave plasma chemical vapor deposition process (MPCVD). For a PAA sample without CNT growth, the reflectance shows an oscillating pattern with wavelength t...
متن کاملFabrication of a porous anodic alumina membrane
With the aim of developing a process for surface enlargement on an electrode for measuring brain activity attempts have been made to fabricate a porous anodic alumina membrane directly on the electrode. The porous membrane was intended to be used as scaffold for deposition of an electrically conducting polymer on the electrode surface. A silicon wafer with gold electrodes was the base onto whic...
متن کاملCylindrical Three-Dimensional Porous Anodic Alumina Networks
The synthesis of a conformal three-dimensional nanostructure based on porous anodic alumina with transversal nanopores on wires is herein presented. The resulting three-dimensional network exhibits the same nanostructure as that obtained on planar geometries, but with a macroscopic cylindrical geometry. The morphological analysis of the nanostructure revealed the effects of the initial defects ...
متن کاملIndependently addressable fields of porous anodic alumina embedded in SiO2 on Si
Fields of thin-film porous anodic alumina !PAA" are fabricated within a SiO2 support and on independently addressable underlying metal pads. The underlying metallization provides a means for unique postprocessing to be performed on the PAA fields. Customized postprocessing is demonstrated with the synthesis of single-walled carbon nanotubes !SWCNTs" from an embedded catalyst in the PAA, followe...
متن کاملAFM, SEM and TEM Studies on Porous Anodic Alumina
Porous anodic alumina (PAA) has been intensively studied in past decade due to its applications for fabricating nanostructured materials. Since PAA's pore diameter, thickness and shape vary too much, a systematical study on the methods of morphology characterization is meaningful and essential for its proper development and utilization. In this paper, we present detailed AFM, SEM and TEM studie...
