Fabrication of alumina films with laminated structures by ac anodization
Anodization techniques by alternating current (ac) are introduced in this review. By using ac anodization, laminated alumina films are fabricated. Different types of alumina films consisting of 50-200 nm layers were obtained by varying both the ac power supply and the electrolyte. The total film thickness increased with an increase in the total charge transferred. The thickness of the individua...
متن کاملEffects of Illumination Porous Silicon During Anodization of
The effects of illumination during anodic etching of porous Si have been studied. For a fixed current density and anodization time, it has been observed that below a critical irradiance level, increasing the radiant flux density during anodization results in higher photoluminescence and a blue shift of the photoluminescence spectra. For irradiance above the critical value, the photoluminescence...
متن کاملCo-Precipitation, Strength and Electrical Resistivity of Cu–26 wt % Ag–0.1 wt % Fe Alloy
Both a Cu-26 wt % Ag (Fe-free) alloy and Cu-26 wt % Ag-0.1 wt % Fe (Fe-doping) alloy were subjected to different heat treatments. We studied the precipitation kinetics of Ag and Cu, microstructure evolution, magnetization, hardness, strength, and electrical resistivity of the two alloys. Fe addition was incapable of changing the precipitation kinetics of Ag and Cu; however, it decreased the siz...
متن کاملA versatile nanopatterning technique based on controlled undercutting and liftoff.
Nanopatterning techniques have applications across a wide range of experimental sciences, from controlling cell growth and function [ 1 ] to improving the effi ciency of thin fi lm solar cells. [ 2 ] Approaches developed by the microelectronics industry such as photon-, ionand electron-beam lithography are highly refi ned, producing features with dimensions of just tens of nanometers. Unfortuna...
متن کاملAnodization: A Promising Nano-Modification Technique
As one of the valve metals (including Ti, Al, Ta, Nb, V, Hf, W), titanium is protected by a thin titanium oxide layer which spontaneously forms on its surface when exposed to air or other oxygen containing environments. This oxide passive layer is typically 2 to 5 nm thick and is responsible for the well-documented corrosion resistance property of titanium and its alloys. Because of this and th...
