Abstract

CaSnO₃, SrSnO₃ and BaSnO₃ transparent conducting oxides were prepared via dip-coating method on Corning® glass substrates using the solutions of hydrothermally pretreated precursors. In this work, we demonstrate a simple and easily scalable technique to achieve high uniformity in transparent conducting oxides (TCOs) exhibiting optoelectronic properties comparable to the films deposited by vacuum-based physical methods. Also the effect of nitrogen doping on the overall optoelectronic performance of the thin films is investigated based on their figure of merit (FOM). The influence of film thickness on transmittance and electrical conductivity was studied. Thin films exhibited FOM values of 2.5 × 10⁻³ Ω⁻¹, alongside high transmittance (>78 %) and reduced sheet resistance (35 Ω sq⁻¹). These improvements are attributed to enhanced mobility facilitated by the use of hydrothermally treated precursors, ensuring uniform deposition suitable for high-performance optoelectronic devices.

期刊介绍： Thin Solid Films is an international journal which serves scientists and engineers working in the fields of thin-film synthesis, characterization, and applications. The field of thin films, which can be defined as the confluence of materials science, surface science, and applied physics, has become an identifiable unified discipline of scientific endeavor.
