But they may be hard to turn off and have high leakage current, threshold voltage, and power consumption. These can be solved by co-doping, which can control the defects and quality of the films. In this study, InLiAlO thin films and TFTs with Li:Al ratios of 1:0, 2:1, 1:1, 1:2, and 0:1 (Li + Al = 10 at%) were prepared using spin-coating. It is found that both dopants significantly reduced defects and oxygen vacancies, and increased compactness. Moreover, with the increase of Al addition, the crystallization was inhibited. Therefore, the corresponding device performance should be improved. The undoped device had moderate mobility, low <em>I</em>_on/<em>I</em>_off, and high subthreshold swing (SS). The TFT doped with 10 at% Li exhibited higher mobility and lower SS, while the one with 10 at% Al doping showed decreased mobility, and improved <em>I</em>_on/<em>I</em>_off and SS. It is inferred that lithium doping promoted the transformation of hydroxides to oxides, forming more oxides and reducing hydroxide-related defects, but may generate oxygen vacancies. The aluminum doping suppressed the formation of oxygen vacancies and inhibited crystallization. After optimization, Li:Al = 2:1 is the best doping ratio, featuring a saturation mobility of 5.30 cm² V⁻¹·s⁻¹, a current on/off ratio of 7.48 × 10⁵, and a sub-threshold swing of 0.25 V/decade. The corresponding films have high smoothness and density, indicating high quality and fewer internal voids. It is suggested that co-doping is a promising strategy for improving the performance of indium oxide-based TFTs.</div></div>","PeriodicalId":18240,"journal":{"name":"Materials Science in Semiconductor Processing","volume":"193 ","pages":"Article 109508"},"PeriodicalIF":4.2,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143696908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, we synthesized Schorl/Pyrite (SP) composite, leveraging schorl's self-polarization electric field to modulate pyrite's energy band structure and improve its charge separation efficiency. Herein, we systematically investigated the tribocatalytic performance of the SP composite. Under stirring conditions, the SP composite achieved a remarkable 93.8 % degradation of methylene blue (MB) within 12 h, significantly outperforming the individual components, schorl and pyrite, which degraded 47.5 % and 22.7 %, respectively.

The primary ROS, particularly hydroxyl radicals (•OH), were mainly produced through a self-Fenton reaction facilitated by tribocatalysis. Furthermore, a possible degradation pathway for MB during the tribocatalytic process was proposed. These results highlight the critical role of schorl's self-polarization in enhancing electron mobility and boosting tribocatalytic efficiency.

At all doping concentrations, the tetragonal phase was retained, according to X-ray diffraction (XRD) examination. Dielectric investigations showed that while the dielectric constant (ε_r') and dielectric loss (<em>ε</em>'') decreased with increasing Eu content, the frequency-dependent improvement of AC electrical conductivity (σ_AC) was ascribed to charge hopping among nanograins and dielectric relaxation impacts. Magnetic studies were presented to explore the ferromagnetic response further, revealing a shift from diamagnetic behavior in pure ZnO to robust room-temperature ferromagnetism (RTFM) in Co-doped and (Co, Eu) co-doped ZnO nanoparticles. Strong carrier-mediated exchange contacts and defect-induced magnetism were shown by the increased remanent magnetization (Mr) and coercivity (Hc) that accompanied increasing Eu content, peaking at 5 % Eu doping. Ferromagnetic ordering with a Curie temperature (T_C) of roughly 370 K for optimally doped materials was validated by Arrott plot analysis. The exchange interactions, defect-induced effects, and structural deformation all contribute to the magnetism in ZnO caused by Co and Eu doping. While Eu³⁺ participates by forming partially filled 4f orbitals, Cobalt (Co²⁺) ions contribute localized magnetic moments because of unpaired 3d electrons when they substitute Zn²⁺ in the ZnO lattice. These dopants interaction facilitates long-range ferromagnetic coupling via carrier-mediated exchange processes, which include bound magnetic polarons (BMPs), in which oxygen vacancies trap charge carriers.
