Abstract
We present on the elaboration and characterization of p-type Mn3O4 thin film grown on ITO substrate, using spray pyrolysis as a low cost growth method. The structural, surface and optical properties of Mn3O4/ITO heterostructure were studied by using (XRD) X-ray diffraction, atomic force microscopy techniques and ultraviolet–visible-near infrared spectrophotometer. It turned out that the optical characteristics of this heterostructure exhibits an improved transmittance in the blue-green spectral range. Moreover, we found that the average grain size for hausmannite films deposited on ITO is equal to 220 nm. The I–V curve of p-Mn3O4/ITO thin film revealed a linear behavior, which can be positively used for optoelectronic devices.
期刊介绍：
Protection of Metals and Physical Chemistry of Surfaces is an international peer reviewed journal that publishes articles covering all aspects of the physical chemistry of materials and interfaces in various environments. The journal covers all related problems of modern physical chemistry and materials science, including: physicochemical processes at interfaces; adsorption phenomena; complexing from molecular and supramolecular structures at the interfaces to new substances, materials and coatings; nanoscale and nanostructured materials and coatings, composed and dispersed materials; physicochemical problems of corrosion, degradation and protection; investigation methods for surface and interface systems, processes, structures, materials and coatings. No principe restrictions exist related systems, types of processes, methods of control and study. The journal welcomes conceptual, theoretical, experimental, methodological, instrumental, environmental, and all other possible studies.
