TL;DR: In this article, the results of an investigation of the nanostructure, elements, and phase composition of thin (100-140 nm) tin dioxide films obtained via magnetron sputtering and containing Ag, Y, Sc, Ag + Y, and Ag + Sc additives in the volume were studied.
Journal ArticleDOI
Oxygen sensors based on gallium oxide thin films with addition of chromium
TL;DR: In this article, the gas-sensitive properties of polycrystalline gallium oxide thin films with chromium additives were revealed, and they showed that the reaction time of the sensor was 20 seconds at 700°C in an initial nitrogen-containing atmosphere at 2 exposure to 21vol% and the recovery time comprised 52 seconds.
Journal ArticleDOI
