ABSTRACTWe have successfully fabricated self-organized GaN nanotips by reactive ion etching using chlorine plasma, and have revealed the formation mechanism. Nanotips with a high density and a high aspect ratio have been formed after the etching. We deduce from X-ray photoelectron spectroscopy (XPS) analysis that the nanotip formation is attributed to nanometer-scale masks of SiO2 on GaN. The structures calculated by Monte Carlo simulation of our formation mechanism are very similar to the experimental nanotip structures.

In this paper, self-organized TiO2 nanotubes (TNT) were synthesized by electrochemical anodization in different electrolytes comprising acidic fluorinated aqueous electrolyte and organic neutral electrolyte. The structural, morphological and composition of TNT were characterized with XRD, FESEM and EDX. Compared with aqueous electrolyte, much smoother tubes with an increase of over 30 times in nanotube length can be obtained by anodization in organic electrolyte. Besides the high aspect ratio, variation of nanotube length within the array could be observed. Interestingly, under the same heat treatment condition, choice of electrolyte has an influence on the crystalline structure of TNT.
