Typically, the structure of ReRAM cells involves a nanoscale layer of resistance-switching material sandwiched between two metal electrodes. The basic question that we ask is what is the optimal driving protocol to switch a memristive device from one state to another. In the case of ideal memristors, in the most basic scenario, the optimal protocol is determined by solving a variational problem without constraints with the help of the Euler-Lagrange equation. In the case of memristive systems, for the same situation, the optimal protocol is found using the method of Lagrange multipliers. We demonstrate the advantages of our approaches through specific examples and compare our results with those of switching with constant voltage or current. Our findings suggest that voltage or current control can be used to reduce Joule losses in emerging memory devices.","PeriodicalId":449,"journal":{"name":"IEEE Transactions on Nanotechnology","volume":"24 ","pages":"8-16"},"PeriodicalIF":2.1,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912459","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}

A facile process-optimized technique for synthesis of gamma iron oxide nanoparticles has been designed in order to investigate the optimum temperature, doping and pH of the sodium hydroxide. By dint of morphological investigation, it has been established that the samples have high surface area, crystalline structure, and size in the range of fifty to hundred angstrom. The linearity of the magnetization feature coupled with its doping sensitivity points towards its usage for state estimation technology of the energy storage device management. The nano-scaled samples witness an increase of 75%–110% in the direct bandgap in comparison to its bulk existence. This band gap modulation establishes that the conductivity can be improved for electrode application by doping. High surface area for the active material ingredient nano-particles has also been confirmed by BET surface area of up to 75 m\u0000<sup>2</sup>\u0000/g.

The NEGF formalism allows us to capture the detailed physical picture of quantum mechanical effects such as electrostatic quantum confinement, resonant tunneling of electrons through barriers in such structures and negative differential resistance. Also, by using NESS capabilities, we have simulated RTDs with Random Discrete Dopants (RDDs) as a source of statistical variability in the device.

In this direction, nanofibers have gained significant attention. However, in many cases, efficient and controlled transfer of nanofibers plays an important role in various device developments. In this study, thermomechanical i.e., temperature and pressure-induced transfer of poly(vinylidene fluoride) (PVDF) electrospun nanofibers on flexible poly(dimethylsiloxane) (PDMS) substrate has been explored. The average diameter of the transferred nanofibers is 169.78 nm. The d\u0000<sub>33</sub>\u0000 of PVDF nanofibers was 25 pC/N and F(β) was found to be 80.84%. The synthesized nanofibers have effectively been transferred onto a flexible PDMS substrate with more than 92% retention of optical transparency. It is observed that the transfer of the fibers depends on the applied pressure and adhesion between the materials. Further, it was found that fully cured PDMS substrate heated at 120 °C showed better transfer efficiency (12.544%) with higher stability. The use of PVDF nanofibers along with the inherent flexibility and transparency of PDMS, renders the produced substrate highly promising for the development of low-cost, lightweight, and easily constructed flexible sensors. Moreover, the fabricated nanofibrous mat generated a maximum voltage of 2.78 V on continuous tapping.","PeriodicalId":449,"journal":{"name":"IEEE Transactions on Nanotechnology","volume":"23 ","pages":"786-793"},"PeriodicalIF":2.1,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142777846","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}
