For biosensor applications, silanes with active terminal groups such as amine, thiol, carboxylic, and aldehyde groups are utilized in routine. In near‐field sensing schemes like biologically sensitive field‐effect transistors, it is crucial to generate a homogeneous layer of silane to confine the biointeractions in close vicinity of the sensor interface. The homogeneity of such biofunctional layer is determined by the surface activation and silanization protocol being applied. Herein, the impact of the surface activation process and silanization on electrical characteristics of field‐effect devices is studied comprehensively using an electrolyte‐oxide‐semiconductor (EOS) capacitor with a high‐quality gate oxide. The thermally grown silicon oxide (SiO2) interface is activated using acidic mixtures and plasma treatment, while the subsequent silanization steps are investigated comparatively using two different silanes (3‐aminopropyl triethoxysilane (APTES) and 3‐glycidyloxypropyl trimethoxysilane (GPTMS) in wet‐chemical and vapor‐phase processes. Furthermore, the optimized silanization process is utilized to immobilize an oligo strand at the EOS capacitor surface, followed by the hybridization of complementary oligo strands. The optimized protocol holds the potential for large‐scale production of functional oxide interfaces for various applications.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81257444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite having so many advantages, the energy efficiency of this technology is extremely low. Therefore, their current performance needs to be improved so that they can be used more in daily life. Nanofibers (NFs) are one of the most important material groups that can be used for this technology due to their large surface area–volume ratio, easy production, low cost, and simplicity. Herein, Nylon 6.6 and polyacrylonitrile are used as tribopositive and tribonegative dielectric layers, respectively. To increase the output performances of the TENG system, different weight ratios (1, 2, 3 wt%) of phthalocyanine containing zinc‐based carborane units (ZnPc) are added into the Nylon 6.6 NFs. In accordance with the obtained results, the maximum open circuit voltage and power are measured as 228 V and 7.76 mW, respectively. These results correspond for the TENG system with 1% by weight ZnPc doped into the NFs. These results show that high‐efficiency TENG systems can be obtained with nanofiber‐based dielectric layers and can be used effectively in self‐powered systems.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80618751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, palladium thin films with carefully controlled surface morphologies are obtained through the careful choice of the reducing agent used during the pre‐plating activation step in the three‐step autocatalytic electroless plating consisting of 1) surface functionalization; 2) surface activation; and 3) deposition of the film onto alumina substrates. It is important to note that the reducing agents that influenced the surface morphology of the palladium thin films are employed in the pre‐plating activation step instead of the widely utilized electroless deposition step. It is revealed in the high‐resolution scanning electron microscope results that the hydrogen reducing agent yields a dense film with 3D spheroidal morphologies with an average cluster size of ≈415 nm while the hydrazine reducing agent produces a very smooth uniform surface morphology consisting of extremely small grains. The obtained results can be exploited in controlling and tailoring the surface‐dependent properties of the palladium thin film for applications in gas sensors, detectors, or palladium‐based membranes.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"180 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86811652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensor is made up of calcium fluoride prism, silver, silicon, and tungsten di selenide nanolayer. The theoretical and numerical study of surface plasmon resonance sensor is analyzed by angle interrogation method with the help of MATLAB 2017b. The transfer matrix method (TMM) is the foundation for simulation and a monochromatic light of wavelength 633 nm is considered as source. In the proposed device structure, each layer is arranged in vertical format to improve the electrical and optical properties. The refractive index for analyte is considered as 1.330 to 1.335. Silver (Ag) metal is used for the generation of surface plasmons. It has good chemical properties like metallic conductivity, chemical stability, bandgap, small work function, and acts as an adhesive layer between calcium fluoride prism and silicon layer. To improve the molecular contact and absorption, the transition metal dichalcogenide nanofilm tungsten di selenide (WSe2) is applied at the top.
