#just_published our article entitled "Plasmonic-Enabled Nanostructures for Designing the Next Generation of Silicon Photodetectors: Trends, Engineering and Opportunities" in the Surfaces and Interfaces journal (Impact Factor: 6.2, CiteScore: 7, Q1). #The article highlights how AgNWs can boost the efficiency of silicon photodetectors by amplifying light absorption and facilitating efficient charge transfer. We discuss the potent synergy between AgNWs and silicon, which results in devices exhibiting significantly higher responsiveness and detectability than their conventional counterparts. This work also presents the nuanced physics of plasmonic interactions at the nanoscale and discusses advanced synthesis techniques and strategies for integrating AgNW networks with silicon. #Read the article https://lnkd.in/eVyD6-mq #Photonics #Nanotechnology #Photodetectors #Plasmonics #ResearchPublication #SiliconPhotodetectors #Innovation

✍ In a little more than 10 minutes, das-Nano and the Terahertz Wave Technology Revolution explained by its Director Israel Arnedo. A month ago, we participated in an online event organized by EPIC - EUROPEAN PHOTONICS INDUSTRY CONSORTIUM around thin films fabrication and characterization. Thin films are basically layers of material that are deposited on any surface, using complex chemical and physical deposition techniques, including gas-phase precursors and plasma process. They are widely used in different markets, such as optics, photovoltaics, telecom/datacom, consumer electronics, medical/healthcare or automotive. To support some of the present technological mega-trends and the last requirements of the different sectors, innovative thin-film materials have to be studied, developed and implemented. These new materials also require special developments for their fabrication and specific tools for the characterization of their physical and optical properties. EPIC invites coating and thin-film manufacturers, machine builders for coating manufacturing, the suppliers of characterization tools and all the end-users of special thin-films to join us to discuss the newest solutions in this field and where are the present challenges and needs.

Excited to share our latest research #https://lnkd.in/ge9_BfFC on the fabrication and characterization of Nickel (Ni) nanodot arrays on Chromium (Cr), a study that opens new avenues for designing nanoscale magnetic systems! 🌟 Using a nano-stencil-assisted electron beam evaporation technique, we successfully deposited Ni nanodots on Cr in two distinct forms—nanodot and continuous layers. The precise patterning was validated through Atomic Force Microscopy (AFM), while the exchange bias properties were explored using Magnetic Force Microscopy (MFM) and Magneto-Optical Kerr Effect (MOKE) magnetometer. This study not only showcases the potential of nano-stencil fabrication as a versatile, streamlined approach but also highlights how the magnetic properties of Cr/Ni structures can be tuned by manipulating the form of Cr deposition. #Nanotechnology #MagneticMaterials #ExchangeBias #NanoFabrication #ResearchInnovation #Spintronics #MaterialsScience

I am looking forward to speaking at 2D-EPL Symposium tomorrow at Brussels during the innovation forum. The talk will focus on capabilities from X-FAB related to Advanced Packaging and Heterogenous Intergration in the field of Photonics. In addition, it will also focus on challenges faced with respect to integration of graphene from a foundry perspective.  #Photonics #MEMS #AdvancedPackaging #HeterogenousIntergation #SiliconPhotonics #Semiconductor #2Dmaterials #Graphene #AdvancedMaterials #Biosensor

Schlieren, Switzerland, March 11th, 2024. EXALOS, the world’s leading manufacturer of Superluminescent Light-Emitting Diodes (SLEDs), has expanded its product portfolio in the red wavelength range with new broadband SLEDs at 633 nm, 638 nm and 680 nm, in addition to its well-established SLEDs at 650 nm. The new 633nm SLEDs deliver a broad optical spectrum with a 3dB bandwidth of 5-7 nm and with a highly polarized free-space output power of 10-15 mW, making them ideal sources for various interferometry applications at the HeNe wavelength of 632.8 nm. These new SLEDs will be also available in 14pin BTF modules with single-mode (SM) or polarization-maintaining (PM) fibers. Due to advanced semiconductor processes developed over the past few years, EXALOS is now able to offer high-power 638nm SLEDs and LDs with a free-space output power of up to 50 mW. This new generation of high-power, single-mode red superluminescent and laser diodes will support various high-end applications, including display and AR/VR architectures. At the upper end of the red emission spectrum, EXALOS is now offering broadband SLEDs at 680 nm with a broad bandwidth of 10 nm, available as 14pin BTF modules with either SMF or PMF output. These devices offer excellent long-term stability and reliability, making them suitable for various industrial applications that require light sources for 24/7 operation over several years.

"High-performance active terahertz (THz) modulators are of great importance for next generation communication technology. However, they currently suffer from the tradeoff between modulation depth and speed. Two-dimensional (2D) materials with unique physical properties such as strong light-matter interactions, atomically thin profile, and fast carrier recombination, could offer an intriguing platform for investigating optoelectronic devices in fundamental physics. Therefore, it is urgent to find the favorable 2D materials that boost device performance." #terahertz #modulators #communications #2dmaterials #materialscience

A new paper is out! Here, we demonstrated state-of-the-art of utilising semiconductor nanostructures to develop thin film photodetectors embedded into the optical fiber for online power applications. The evanescent field of propagating mode was drawn out of the fiber, increasing the light interaction with semiconductor nanostructures, leading to generation of photoexcited electron-hole pairs. The unique properties of these wide bandgap nanostructures can open the door for next-generation optoelectronic devices with improved performance. I'm incredibly grateful to the editorial board of #PhysicaScripta, #InstituteofPhysics (IOP), for maintaining such high standards throughout the journey from initial submission to publication. #Optoelectronics #Nanostructures #PorousSemiconductors #Photodetectors #MaterialsScience

Exciting developments in spintronics have emerged from researchers at CIC nanoGUNE BRTA, who have successfully engineered a groundbreaking 2D graphene spin valve leveraging van der Waals magnet proximity. Published in Nature Electronics, this innovative device utilizes proximity effects to manipulate and transport electron spin in a streamlined 2D configuration. Unlike traditional designs, the absence of physical interfaces reduces spin loss, enhancing performance. The all-proximitized spintronic device draws on fundamental discoveries from the 1980s, building on the principles of spin injection and demonstrating potential advancements in "proximitronics." Featuring a singular graphene piece functionalized by the magnetic insulator Cr2Ge2Te6, this technology exhibits promising spin-orbit and magnetic exchange coupling. The research team's immediate focus is further exploration into these advancements, which may form the basis for a new research field. This innovation represents a significant stride in understanding the proximity effect's role in spintronic applications, inspiring future research into this transformative technology. #Spintronics #Graphene #Innovation
