Název v původním jazyce

Effect of annealing on composite nanoparticle-based thin films for improved hydrogen gas sensing

Popis výsledku v původním jazyce

This study delves into the advancement of conductometric gas sensors, specifically focusing on optimizing the sensorial response through nanostructuring of metal oxide semiconductors. Composite thin films composed of p-type CuO and n-type WO3 nanoparticles (NPs) were deposited using the Nanogen-Trio NP source with custom-built chamber and DC power supply in Ar+O2 gas mixture. A sophisticated in-house developed software was used to achieve precise deposition of NP-based thin films with defined volumetric ratio of CuO and WO3 NPs. It was also observed that the addition of O2 enhances NP mass flux and allows for stoichiometry tuning. The study demonstrates the versatility of our custom-built gas aggregation source (GAS) that facilitates the preparation of composite NP-based thin films and a novel approach to enhance the performance of gas sensors by tailoring nano p-n heterojunctions.
