Abstract:
To study the dependence of the relative stability of surface (V ( A )) and subsurface (V-B ) oxygen vacancies with the crystal facet of CeO2, the reduced (100), (110) and (111) surfaces, with two different concentrations of vacancies, were [read more]

Correlation between structural and morphological properties of multilayer perovskite ZnTiO3 coated porous silicon

Authors: Khadija, H; Khalifa, M; Alvarez-Galvan, MC; Ezzaouia, H

Article.
Eur. Phys. J.-Appl. Phys. vol: 93. page: 1286-0042.
Date: jun-21. 2021.
Doi: 10.1051/epjap/2021210016.

Abstract:
This work reports on correlation between structural and morphological properties of ZnTiO3/porous silicon (PS). The PS was elaborated by electrochemical anodization from the single- crystal p-type silicon wafer. Nanocrystalline ZnTiO3 thinfilms have been prepared on PS using sol-gels [read more]
