The primary goal of this paper is comparing the various parameters for a few biomolecules including APTES (3-aminopropyltriethoxysilane), keratin, staphylococcal nuclease, and gelatin with varying dielectric constant values. The biomolecules with distinct dielectric constants are positioned inside the nanocavity near the sides of the channel of the device structure, which allows for the observation of the changes of the drain current versus gate voltage characteristic graph. Substantially improving the output characteristics of the proposed V-TFET, the dual metal work function designs improve the sensitivity of the GaAs-hetero-V-TFET biosensor. By incorporating distinct biomolecules, several electrical metrics, including drain current, electric field, threshold voltage, electron band-to-band tunneling rate, and drain current sensitivity, changed significantly. With an excellent subthreshold swing (14.45 mV/dec), the biosensor can detect a maximum ON-current of 6.64 × 10⁻⁵ A/µm and an OFF-current of 2.36 × 10⁻¹⁸ A/µm for the gelatin at κ = 12. The biosensor's sensitivity of κ = 12 has been determined by studying both neutral and charged biomolecules. The provided biosensor explored the transconductance sensitivity at 9.43 × 10⁵ and the drain current sensitivity at 2.61 × 10⁶. Finally, compared to earlier reported investigations, it has been demonstrated that the presented biosensor device produces superior sensitivity.</p></div>","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"54 11","pages":"9855 - 9864"},"PeriodicalIF":2.5,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145230436","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}

Under violet excitation, ceria NPs have a strong emission in the visible region (~530 nm), which clearly proves its strong fluorescent behavior. Here, Au NPs are embedded <i>in situ</i> with CeO₂ NPs. In addition, the second harmonic generation (SHG) of poly{1-[<i>p</i>-(3′-carboxy-4′-hydroxyphenylazo)benzenesulfonamido]-1,2-ethandiyl, sodium salt} (PCBS) and its fluorescence response with light emitting diode (LED) excitation at 780 nm were studied. The Stern–Volmer constant of PCBS in peroxide detection is 0.0987 M⁻¹, lower than the value of ceria, which is 0.1419 M⁻¹. Afterwards, the system is applied in the field of peroxide sensing in aqueous media. The fluorescence intensity is found to be affected by the addition of peroxides into CeO₂-Au NPs. The Stern–Volmer quenching constants were found to be 0.0987 M⁻¹ for PCBS, 0.1419 M⁻¹ for undoped ceria, and 0.1763 M⁻¹ for Au-doped ceria, indicating a 26.72% enhancement in sensitivity. The sensitivity of ceria NPs in peroxide quencher detection is found to be enhanced considerably by the addition of Au NPs. This is because of the plasmonic resonance of Au NPs as it is optically coupled with the fluorescence emission spectrum of ceria. The bandgap of ceria is also found to be decreased by the addition of Au NPs, which is due to the creation of more oxygen vacancies inside the nonstoichiometric crystalline structure of ceria. The sensitivity of the optical sensing material, ceria–gold NPs with added peroxide, is characterized by the Stern–Volmer constant and is found to be 0.1763 M⁻¹ which is higher than the case of using ceria NPs only. Ceria–gold NPs with enhanced optical sensitivity can be employed as an optical sensing host for peroxides, which plays a major role in many important applications such as biomedicine and water quality monitoring. This work introduces a novel dual-mode optical sensing platform by integrating the SHG response of PCBS thin films and the plasmon-enhanced fluorescence quenching behavior of Au-doped CeO₂ nanoparticles.

These challenges lead to uneven energy distribution and thermal damage, compromising device performance. In this study, we present a novel approach utilizing a 193 nm ArF excimer laser for non-thermal laser contact opening (LCO) to improve energy uniformity and minimize heat-affected zones in 100-μm-thick, 6-inch single-crystal silicon solar cells. The excimer laser enables large-area, uniform ablation with reduced substrate damage, in contrast to traditional 1064 nm picosecond lasers. Comparative analysis demonstrated that the excimer-based LCO achieved a 1.04% increase in fill factor (from 78.92% to 79.96%) and a 0.35% improvement in power conversion efficiency (from 19.79% to 20.14%), along with a reduction in series resistance by 0.00054 Ω. These improvements are attributed to enhanced LCO width uniformity and edge definition. This work highlights the significant potential of excimer lasers for precision back-contact structuring in high-efficiency, thin-film photovoltaic technologies.

Three quantum dot-based photoanodes were fabricated: (i) CNT–La₂O₃, (ii) cerium-doped CNT–La₂O₃ (CNT–La_1.5Ce_0.5O₃), and (iii) cerium and cobalt co-doped CNT–La₂O₃ (CNT–La_1.0Ce_0.5Co_0.5O₃). These materials were deposited on fluorine-doped tin oxide (FTO) substrates using the chemical bath deposition method. x-Ray diffraction analysis confirmed the successful incorporation of cerium (Ce³⁺/Ce⁴⁺) and cobalt (Co²⁺/Co³⁺) ions into the CNT–La₂O₃ matrix, leading to structural distortion and enhanced crystallinity. Atomic force microscopy revealed that CNT–La₂O₃ provided a well-balanced surface morphology, ensuring consistent charge transport and improved dye adherence. The incorporation of Ce ions increased defect density and surface roughness, facilitating higher dye-loading capacity and improved light scattering. In addition, cobalt ion inclusion contributed to anisotropic features and localized electronic heterogeneity, optimizing electron pathways. Ultraviolet–visible (UV–Vis) spectroscopy revealed red shifts in absorption edges, suggesting enhanced photon harvesting in the visible spectrum. A sequential reduction in bandgap across the series further demonstrated the pivotal role of Ce and Co in modulating the electronic structure of CNT–La₂O₃. DSSCs fabricated with CNT–La_1.0Ce_0.5Co_0.5O₃ exhibited the highest photon conversion efficiency of 12.50%, outperforming other configurations.

Polyethylenimine-functionalized cerium dioxide-supported platinum nanoparticles (PEI-CeO₂@PtNPs) were used for the modification of electrodes. The nanocomposite enhanced electrical conductivity on the electrode, and provided more attachment sites to increase the loading capacity of aptamer chains. Additionally, polyethylenimine-functionalized melamine-cyanuric acid condensation polymers (PEI-MCA) were used as carrier for the signal probe. Because of the unique porous structure and abundant functional groups on the surface of MCA, the loading efficiency of methylene blue (MB) was significantly enhanced, and the complementary DNA (cDNA) strand of aptamers was effectively loaded on PEI-MCA by strong electrostatic interaction to construct signal probes. The cDNA was captured by aptamers through complementary base pairing, and PEI-CeO₂@PtNPs amplified electrical responses cooperatively with PEI-MCA. In the presence of FB1, the aptamers preferentially bound to FB1, and the signal probes were detached from the electrode surface, resulting in a decrease in the electrochemical response.
