Thickness, composition and morphology of the oxide films were determined by various surface analytical techniques such as Auger electron spectroscopy, X-ray photoelectron spectroscopy, scanning and transmission electron microscopy and atomic force microscopy. The oxides comprise mainly In 2 O 3 and Sb 2 O 3 and the oxide thickness increases with pH. Electrical properties of oxides indicate that the films may be useful as insulators in some device applications.

Characterization of thin InP anodic oxide layers: Correlation of morphological investigations with chemical and electrical properties

“…4c). Similar observations have been performed for the anodic oxidation of n-InSb in NaOH [15]. Although a compact and dense oxide film was grown at low applied current, a stressed, rough and porous film covered by hemispherical features was formed when high current was used.…”

Trap-assisted conductivity in anodic oxide on InSb

“…Further, it is generally believed that the oxide is amorphous in its nature. However, presence of nanocrystallites in the amorphous phase and formation of microcrystalline structure were observed as well [5,16]. So, the values of electron effective mass m* = 0.2…0.3m 0 , which was reported in the literature for polycrystalline films and single crystals [18][19][20] [21].…”

“…of works [12][13][14][15][16]. Because of contradictory data were obtained, studies of electrical conductivity remain important in order to clarify the role of native defects in the anodic oxide.…”

“…The peak positions appear at 529.8 and 539.7 eV for Sb 3d 3/2 , Sb 3d 5/2 , respectively, which matches well with the literature values of Sb 3? species for both catalysts [30,31].…”
