New Parameter in Polymer - Assisted Sol - Gel Deposition

TL;DR

This paper introduces a new parameter, shaking of the sol, in the Polymer Assisted Sol-Gel Deposition process, which reduces the formation of undesired [111]-oriented CeO2 grains on SrTiO3 substrates.

Contribution

It proposes and tests a novel parameter, shaking, to improve film quality in the polymer-assisted sol-gel deposition method.

Findings

Shaking decreases [111]-oriented CeO2 grains significantly.

The new parameter improves film uniformity.

Method enhances control over grain orientation.

Abstract

In this work a new parameter for the Polymer Assisted Sol- Gel Deposition method is proposed. It is shaking of the sol stabilized by the polymer prior to the deposition. It was found in attempt to decrease the amount of [111]- oriented CeO2 grains on a monocrystalline substrate SrTiO3 (001). It was found that the shaking decreases this amount significantly.
