In this work, SnO₂ nanoparticle-anchored MoS₂ nanoflowers were prepared using a cost-effective two-step hydrothermal synthesis method, in which MoS₂ nanoflower petals loaded with SnO₂ nanoparticles demonstrate engineered surface properties and a heterostructure interface suitable for NO₂ gas-sensing applications. The surface morphology and composite composition were investigated using field-emission scanning electron microscopy (FESEM), energy-dispersive x-ray spectroscopy (EDS) mapping, and transmission electron microscopy (TEM) characterization techniques, which confirmed the growth of SnO₂ nanoparticle-anchored MoS₂ nanoflowers. Structural characterization and elemental composition were confirmed by x-ray diffraction (XRD), Raman spectroscopy, and x-ray photoelectron spectroscopy (XPS) characterization. The developed sensor demonstrates a significantly increased sensor response of 73% compared to the as-grown MoS₂ nanoflower sensor, with a response of 32.02% for 100 ppm NO₂ at an operating temperature of 100°C. The gas-sensing mechanism is driven by large active sites and heterojunctions at the interfaces of SnO₂/MoS₂, which support enhanced sensor response. The developed sensor shows an increase in the relative response from 12.32% to 73% for NO₂ gas concentrations ranging from 0.1 ppm to 100 ppm at 100°C. This optimized sensor demonstrates enhanced sensitivity and selectivity towards NO₂ gas, with a limit of detection (LoD) of 58.8 ppb and a fast response time of ~27 s.</p></div>","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"55 11","pages":"9507 - 9520"},"PeriodicalIF":2.8,"publicationDate":"2026-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the transport mechanisms and optoelectronic behavior of Cs₂AgSbI₆ were investigated by combining impedance spectroscopy, electrical transport, photoluminescence, and optical absorption measurements. The results reveal a highly disordered electronic structure characterized by non-ideal charge transport, strong photoluminescence quenching, and relatively large Urbach energy (~90 meV), indicating significant density of localized states near the band edges. To further examine the influence of these experimentally observed limitations at the device level, SCAPS-1D simulations were performed using a representative fluorine-doped tin oxide (FTO)/TiO₂/Cs₂AgSbI₆/Spiro-OMeTAD architecture. The simulations suggest that defect-assisted Shockley–Read–Hall (SRH) recombination plays an important role in limiting carrier transport, quasi-Fermi-level splitting, and photovoltaic response. Qualitative agreement was obtained between the experimental observations and the numerical trends, supporting the interpretation that defect-related disorder strongly influences carrier dynamics in Cs₂AgSbI₆. These findings provide insight into the relationship between optoelectronic disorder, non-radiative recombination, and charge transport in lead-free double perovskites and highlight the importance of defect passivation and improved crystallinity for future optoelectronic applications.</p></div>","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"55 11","pages":"9677 - 9696"},"PeriodicalIF":2.8,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
