A Q‐switched Nd:YAG pulsed laser beam is used for the ablation process. The fabricated NP films are postirradiated by the pulsed laser beam. In addition, as‐deposited NP films are annealed in argon gas flow ambient for 45 min at different temperatures (250, 350, and 450 °C), and also annealed at 450 °C for 15, 30, and 45 min. The characteristics of fabricated NP films are investigated after postirradiating by pulsed laser beam, and thermal annealing in Ar gas flow. UV–vis absorption spectroscopy is utilized to provide surface plasmon resonance (SPR) characteristics of films. The results show that thermal annealing can lead to strong enhancement, and also narrowing of the SPR spectrum. The results of field emission scanning electron microscopy and atomic force microscopy show that the annealing and postirradiation processes can influence the NPs size and film structure. As an application, the fabricated film is utilized for surface‐enhanced Raman spectroscopy (SERS) using a 10−6 molar aqueous solution of Rhodamine 6G. The SERS results indicate that the annealed NP films become more sensitive than the as‐deposited films.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"193 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79785683","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}

Sobolev","doi":"10.1002/pssa.202300298","DOIUrl":"https://doi.org/10.1002/pssa.202300298","url":null,"abstract":"A spectre is haunting the globe—the spectre of a revolution in electronic devices. The inevitability of this revolution is dictated by the emergence of new paradigms of electronics, such as neuromorphic computing, which cannot be implemented on existing hardware. One of the key enablers of the new paradigms is the memristor (resistor with memory). The latter is often based on the electrical resistive switching (RS) phenomenon. However, the memristive systems include also capacitive and inductive elements, namely, capacitors and inductors whose properties depend on the state and history of the system. Besides the classical resistive memories, quantum effects may open up new horizons for the implementation of new information storage and processing capabilities, e.g., in superconducting quantum circuits, quantum photonic devices, or using tunnelling and exciton-polariton interaction processes. The respective devices may find application in neuromorphic systems to simulate learning, adaptive, and spontaneous behavior. The symposium “Resistive switching: physics, devices and applications” held in the framework of the 16th International Conference on Nanostructured Materials (NANO 2022, 6–10 June 2022, Seville, Spain) was dedicated to all aspects of resistive switching from theory and modelling through novel materials to circuit elements and system design. The main RS-related hot topics covered by the articles are as follows: • Resistive switching mechanisms • Theory and modelling • Novel memory materials • Experimental techniques • Electrical transport • Memory cells and arrays • Circuit elements with memory • Neural networks, bio-inspired electronics, and bio-interfaces • Quantum memristive systems • Memcomputing • Unconventional computing hardware • Information security hardware The program of the symposium comprised a total of 10 invited and 33 oral talks, as well as 14 poster presentations. The presenters came from 16 countries located on 4 continents: Asia, Europe, and North and South America. Seven presentations have been selected for publication in a dedicated Special Section of physica status solidi (a). Maldonado et al. (article no. 2200520) address the most important hurdle to progress in the development of resistive memories which is the so-called cycle-to-cycle variability which is inherently rooted in the resistive switching mechanism behind the operational principle of these devices. To achieve the whole picture, variability must be assessed from different viewpoints going from the experimental characterization to the adequation of modelling and simulation techniques. The authors show how this variability can be extracted and analyzed for such main parameters of resistive switching as the SET and RESET voltages/currents and how it depends on the methodology used and experimental conditions.

Detailed structural and compositional characterizations are performed using X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM), and energy‐dispersive spectroscopy (EDS). Also, the amount of nitrogen doping has been optimized using different concentrations of the precursor solutions and they are subjected to different postannealing environments. The postannealing process is found to alter the defect structure in ZnO significantly. The samples showing the highest nitrogen doping are further evaluated in detail to know their structural variations. The incorporation of nitrogen into the ZnO structure and the effects of the postannealing process substantially alter the electrochemical characteristics by changing the surface properties of ZnO nanosheets. The effect of these structural variations on the electrochemical performance of ZnO is also explored. Under optimized conditions, the highest conductivity of N‐ZnO nanostructures obtained suggests the material as an outstanding candidate for electrochemical applications.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"30 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78351645","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}

One way of accomplishing this task is by glancing angle deposition (GLAD). Herein, thin Co layers have been deposited using GLAD magnetron sputtering on MgO(001) and MgO(110) substrates. For Co films on MgO(001), the in‐plane anisotropy direction can be directly controlled via the deposition angle. In contrast, for Co on MgO(110), the anisotropy due to the deposition angle competes with the anisotropy induced by the substrate, while the growth parameters determine which contribution dominates. On the other hand, while on MgO(001) the deposition angle as well as the film thickness affect the strength of the Co in‐plane anisotropy, no influence of these parameters on the magnetic properties is found for films on MgO(110).","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83420108","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}
