The chemical composition of surface oxides grown on GaAs was investigated using x-ray
diffraqtion techniques. Native oxides were prepared by exposing the GaAs to HCI and HNO3 …

Anodic dissolution of a GaAs (100) face was investigated by in situ electrochemical atomic
force microscope (AFM). While no surface structure change was observed at− 0.6 V (vs …

A novel two-tier nanostructure with narrow mouth and wide abdomen in porous anodic
alumina (PAA) has been successfully fabricated by an improved two-step anodization in …

Electrochemical treatment of crystalline GaAs in 1 M HCl results in the formationof porous
GaAs. As a by-product of the electrochemical dissolution process, small transparent crystals …

We discovered a unique formation of serrated nanopore in porous anodic alumina (PAA). A
new growth model is proposed for the formation mechanism of PAA. The model emphasizes …

In this paper we present the extremely peculiar electrical properties of nanoporous Ge. A full
and accurate electrical characterization showed an unexpected and extremely high …

Most anodizations of Al to obtain porous anodic alumina (PAA) are conducted in acid
solution including sulfuric acid, oxalic acid and phosphoric acid solutions. It is well known …

Porous anodic alumina (PAA) membranes were fabricated using anodization of Al foils.
Based on morphology observations and photoluminescence (PL) measurements, it is …

We investigate the morphology of porous layers obtained by electrochemical anodization of
(100)-oriented n-type GaP substrates before and after a preliminary 5-MeV Kr implantation …

Ultra-thin alumina films with self-ordered cylindrical vertical pores were fabricated on a p-
type silicon substrate by anodization of Al films with thickness in the range of 30–500 nm in …
