Perovskite nanostructures obtained by a hydrothermal electrochemical process

Increasing the miniaturisation is a key factor in the manufacturing process of the new, high-performances electronic devices. Thin/thick films represent a solution for the miniaturisation and the films can be obtained by different techniques such as RF sputtering, vacuum evaporation, laser ablation, CVD, sol–gel processing, hydrothermal electrochemical procedures. The aim of the paper is to investigate the hydrothermal electrochemical synthesis of perovskite nanostructured thin films. The influence of the synthesis parameters (pH, substrate, current density, temperature) on the composition, morphology and microstructure of the films was studied.
