“…Several approaches have been developed to fabricate ideally longrange-order AAO template without domain boundaries by prepatterning the starting Al films. 17,18 Also it is interesting to note that some GaN walls ͑areas between pores͒ are dislocation-free as shown in the crosssectional transmission electron microscopy ͑TEM͒ image FIG. 1.…”

Ordered GaN nanostructures, i.e., nanopore and nanodot arrays, have been demonstrated by combining a nonlithographic nanopatterning technique and nanoscale selective epitaxial growth. Hexagonal-close-packed nanopore arrays were fabricated in GaN surfaces and SiO2 surfaces on GaN films by inductively coupled plasma etching using anodic aluminum oxide templates as etching masks. Selective area growth through nanopores in SiO2 by metal organic chemical vapor deposition results in ordered GaN nanodot arrays with an average dot diameter and height of 60 and 100nm, respectively. The diameter and density of the GaN nanopore arrays and nanodot arrays are controlled by that of the anodic aluminum oxide template, which can be tuned in a wide range by controlling the anodization conditions. Applying anodic aluminum oxide as an etching mask provides an effective nonlithographic and free of foreign catalysts method to fabricate ordered and dense nitride nanostructures for either bottom-up or top-down technique in the application of high efficiency nitride light emitting diodes.

“…Several strategies such as templating [7,[11][12][13][14][15], self-assembly [16][17][18] and ''breath figures" (BFs) method [19][20][21][22][23][24][25][26], have been developed for fabricating micro-porous materials. Among these methods, BFs is a simple and versatile technique which can dynamically control both the pore formation process and the morphology of the resultant pores [27,28].…”

“…To obtain highly ordered monodomain alumina with uniform nanopores, two major approaches based on the aluminum pretexturation have been developed. After electropolishing, aluminum can be nanoidented with techniques such as fast ion bombardment [145,146,150,202], atomic force microscopy [97], or scanning probe microscopy [167] (Fig. 5).…”

Anodic aluminum oxide (AAO) consists of parallel pores arranged in a honeycomb-like array. Since a two-step self-organized approach in anodic alumina fabrication was invented, tremendous attention was paid to this material. Structural features of anodic alumina, like pore diameter, interpore distance, and nanoporous oxide thickness, can be fully controlled by operating conditions, including type, concentration and temperature of the electrolyte, applied voltage, and duration of the anodization process. Moreover, these operating conditions have also a major impact on the nanoporous array arrangement. Quantitative arrangement analysis methods employing fast Fourier transforms have been developed to assess the nanopores' arrangement. The most frequent application of the anodic aluminum oxide is a template-assisted fabrication of nanostructures. Templates made of the AAO are being successfully applied in fabrication of nanowires, nanotubes, and nanodots by using diversity of techniques, including electrochemical deposition, physical and chemical vapor deposition, sol-gel techniques, etc. Due to the size of obtained nanostructures, magnetic, electric, piezoelectric, luminescent, and catalytic properties of the deposited materials can be significantly improved. Thus, control of the nanopores' structural features and arrangement is crucial for AAO applications in nanotechnology.
