TL;DR: In this paper, the effect of ZnS layer deposition temperature on the properties of the metal oxide p-n heterojunction was investigated by different techniques, and the Mott-Schottky analysis confirmed the n-type conductivity for ZnO and Zns, and p-typeconductivity for the Cu2O layer, respectively.
Effect of the thickness of the ZnO buffer layer on the properties of electrodeposited p-Cu2O/n-ZnO/n-AZO heterojunctions
TL;DR: In this paper, the effect of the thickness of the buffer layer on the properties of the heterojunction was investigated by means of a number of techniques, including Mott-Schottky electrochemical impedance analysis and X-ray diffraction analysis.

Influence of deposition potential on the electrochemical growth and photocatalysis performance of SnO2 nanostructures
TL;DR: In this article , the effect of the deposition potential on characteristics, phase compositions and photocatalysis performances of SnO 2 nanostructures was investigated using a cyclic voltammetry experiment.
Electrochemical growth and characterization of Cu2O:Na/ZnO heterojunctions for solar cells applications
TL;DR: In this paper, the effects of the doping concentration of Na on the electronic, morphological, microstructural, optical and electrical properties of the nanostructures were investigated.
