Avalanche #resistive #switching is the key process that causes a sudden change in electrical properties in solid-state #devices under intense electric fields. Despite its importance for #information #processing, #ultrafast #electronics, #neuromorphic #devices, #resistive #memories, and #brain-inspired #computation, the nature of local stochastic fluctuations driving metallic region formation within the insulating state remains elusive. Using operando X-ray nano-imaging, Claudio Giannetti and colleagues captured the origin of resistive switching in a V₂O₃-based device, revealing #volatile #electronic #switching triggered by nanoscale topological defects in the insulating phase's order parameter. This discovery enables #strain-#engineering approaches for dynamic control of electronic #Mott #switching, with implications for #quantum #materials like transition metal oxides, chalcogenides, and kagome metals.

A transmission electron microscope is just one of the tools we use to analyze your samples. Using an electron beam to create an image, it allows us to view structures at the nano- or atomic-scale. It relies on the wave-particle duality of matter, using the tiny wavelength of electrons to resolve such small features. From analyzing nanoparticles to finding impurities, and from forensics to failure analysis, TEMs are versatile and precise. With nanotechnology at the forefront of innovation today, TEMs are indispensable for analysis and assurance of such tech. Need a custom analysis for minuscule material features?

Happy to share this paper reporting that nanostructured cluster-assembled Pt films show resistive switching activity, negative differential resistance, and reversible memory effects. These properties allow the use of nanostructured Pt films in programmable analog circuits, such as gain amplifiers and relaxation oscillators with fast response. As already demonstrated for cluster-assembled Au films, Pt nanostructured films can be exploited as a novel class of neuromorphic systems for the fabrication of electronic devices.

Publication News! The article "Coupled mode theory-based analytical model of a ring resonator refractive index sensor incorporating bending loss and dispersion" has been published in Photonics and Nanostructures - Fundamentals and Applications (Elsevier). Abstract This paper presents an analytical model of a silicon nitride-based 2D ring resonator refractive index (RI) sensor using coupled mode theory (CMT). The proposed model decomposes the ring resonator into two coupling regions and employs coupled-mode equations to describe input and output amplitudes via scattering matrix analysis. The proposed sensor, operating with varying refractive indices in the background cladding, demonstrates a sensitivity of 218 nm/RIU and a total quality factor of 1198. A comprehensive analysis of the bending loss in the proposed sensor is conducted, elucidating its impact on sensitivity, coupling quality factor, and intrinsic quality factor. This analysis aids in the selection of optimal ring resonator parameters, including radius, width, and gap, to achieve superior sensing performance. Furthermore, the paper examines the effect of dispersion on sensitivity and quality and compares the results with those obtained from CMT-based silicon core ring resonator and disk resonator RI sensors. This study provides valuable insights for the design and optimization of high-performance silicon nitride-based RI sensors for various applications.
