Fabrication of nanomaterials using porous alumina templates
Nanofabrication by self-organization methods has attracted much attention owing to the fact that it enables mass production without the use of expensive lithographical tools, such as an electron beam exposure system. Porous alumina can be fabricated electrochemically through anodic oxidation of aluminum by means of such a self-organization method, yielding highly ordered arrays of nanoholes sev...
متن کاملFabrication of Nanostructured Thin Films using Porous Alumina Templates
We demonstrate a method for fabricating a variety of nanostructured metallic thin films by using one simple approach based on the use of anodic aluminum oxide (AAO) membrane as masking template. Highly-ordered large-area metallic nanoporeor nanotip-arrays (e.g., Ni, Ag, Au), with various sizes and shapes, were deposited onto AAO membranes through e-beam evaporation. Free standing nano-patterned...
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 کاملControlled fabrication of patterned lateral porous alumina membranes.
Confined lateral alumina templates are fabricated with different pore sizes by changing the acid electrolyte and the anodization voltage. The control of the number of pore rows down to one dimension is also achieved, by controlling the thickness of the starting aluminum film as well as the anodization voltage. We observe that the mechanism of pore formation in the lateral regime is very similar...
متن کاملFabrication of Porous Anodic Alumina with Ultrasmall Nanopores
Anodization of Al foil under low voltages of 1-10 V was conducted to obtain porous anodic aluminas (PAAs) with ultrasmall nanopores. Regular nanopore arrays with pore diameter 6-10 nm were realized in four different electrolytes under 0-30°C according to the AFM, FESEM, TEM images and current evolution curves. It is found that the pore diameter and interpore distance, as well as the barrier lay...
