Столбиковые Ниобиевые Оксидные Наноструктуры: Механизм Образования, Микроструктура И Электрофизические Свойства

Abstract

The morphology and microstructure of the columnar niobium oxide nanostructures were investigated. The dependences of their morphological sizes on the anodization voltages (100–450 V) and anodic alumina pore diameters (40–150 nm) were established. The features of ion transfer in the process of niobium local anodizing were investigated and the transport numbers of electrolyte anions and niobium cations were calculated. The formation and growth mechanism was proposed and discussed. The phase composition and electrophysical properties of the column nanostructures were investigated.
