CdTe/GaAs Nanodot Arrays and Carbon Nanotubes Prepared Utilizing Nanoporous Alumina Templates

다국어 초록 (Multilingual Abstract)

Nanoporous alumina templates were prepared by anodizing grain-free aluminum at constant voltage. The self-assembled hexagonally close-packed alumina cell result in ordered cylindrical nanohole arrays with interpore spacings ranging from 50 to 150 nm and pore sizes from 25 to 120 nm. Long-range-ordered CdTe nanodot arrays with controlled size and density were grown on GaAs substrates by using molecular-beam epitaxy with ultrathin nanoporous alumina masks; uniform dot sizes in the ranges of 35 nm (with a density of 2.5 10¹0 cm-²) and 80 nm (with a density of ~8.1 x 10 9 cm-²) were prepared as replicas of the alumina masks. The specic capacitances of the carbon nanotube (CNT) electrodes for electrochemical double-layer capacitors were significantly enhanced, a maximum value of 175 F g-¹, by using the nanoporous alumina/aluminum templates with high pore density and uniform pore diameter.
