Ultrahigh density well-registered oxide nanocapacitors are very essential for large scale integrated microelectronic devices. We report the fabrication of well-ordered multiferroic BiFeO3 nanocapacitor arrays by a combination of pulsed laser deposition (PLD) method and anodic aluminum oxide (AAO) template method. The capacitor cells consist of BiFeO3/SrRuO3 (BFO/SRO) heterostructural nanodots o...

Nanochannel arrays were fabricated by the self-organized multi-electrolyte-step anodic aluminum oxide [AAO] method in this study. The anodization conditions used in the multi-electrolyte-step AAO method included a phosphoric acid solution as the electrolyte and an applied high voltage. There was a change in the phosphoric acid by the oxalic acid solution as the electrolyte and the applied low v...

Crystalline zinc tin oxide (ZTO; zinc oxide with heavy tin doping of 33 at.%) nanowires were first synthesized using the electrodeposition and heat treatment method based on an anodic aluminum oxide (AAO) membrane, which has an average diameter of about 60 nm. According to the field emission scanning electron microscopy (FE-SEM) results, the synthesized ZTO nanowires are highly ordered and have...

The photoluminescence emission of nanoporous anodic aluminum oxide films formed in phosphoric acid is studied in order to explore their defect-based subband electronic structure. Different excitation wavelengths are used to identify most of the details of the subband states. The films are produced under different anodizing conditions to optimize their emission in the visible range. Scanning ele...

A novel and convenient one-pot electrodeposition approach has been developed for precisely controlled fabrication of large-scale Bi-Ni nanowire and nanocable arrays. Using porous anodic aluminum oxide as a shape-directing template, by simply changing the electrochemical deposition mode, desired Bi-Ni hybrid nanowires and Bi-Ni core-shell nanocables have been obtained in the CV and CC modes, res...

Plasma sputtering deposition of Platinum thin films is studied on porous anodic aluminum oxide (AAO) template. The size effect of AAO cylindrical pores is shown to influence the diffusion of atoms in the porous layer. The resulting maximum reached depth of platinum varied from 2 μm to 20 μm, and the density on the surface is lowered from 23 μg.cm to 5 μg.cm as the pore diameter increased from 4...

With a bottom-up assemble technology, heterogeneous magnetic nanobrushes, consisting of Co nanowire arrays and ferromagnetic Fe70Co30 nanofilm, have been fabricated using an anodic aluminum oxide template method combining with sputtering technology. Magnetic measurement suggests that the magnetic anisotropy of nanobrush depends on the thickness of Fe70Co30 layer, and its total anisotropy origin...

NiCu alloy nanowires arrays were embedded into the anodic aluminum oxide (AAO) template by ac-pulse electrodeposition. Different off-time were used in electrolyte with constant concentration of Ni and Cu and acidity of 3. The effect of deposition parameters on alloy contents was investigated by studying the microstructure and magnetic properties of as-deposited NiCu alloy nanowires. Atomic forc...

Ordered and encapsulated 2-D arrays of silver nanoparticles have been fabricated for applications as reliable, durable, reproducible, and high sensitivity sensors and photoconductors based on plasmon resonance enhanced local electromagnetic fields. Silver nanopartilces are encapsulated by anodic aluminum oxide or atomically thin graphene to isolate silver from adverse environmental effects. In ...

The novel nanostructures are fabricated by the spatial chemical modification of nanowires within the anodic aluminum oxide (AAO) template. To make the nanowires better dispersion in the aqueous solution, the copper is first deposited to fill the dendrite structure at the bottom of template. During the process of self-assembly, the dithiol compound was used as the connector between the nanowires...
