Ion Beam Modification for Si Photonics | Article by Lyudmila V. Goncharova and Peter J. Simpson https://lnkd.in/gh8dHnUZ Western University; The University of British Columbia; MDPI #IonBeam #Photonics #Silicon #quantumdot #physics This article belongs to the Special Issue: Selected Papers from Applied Nuclear Physics Conference 2021 https://lnkd.in/ghJdaRhH #Abstract Ion implantation has played a significant role in semiconductor device fabrication and is growing in significance in the fabrication of Si photonic devices. In this paper, recent progress in the growth and characterization of Si and Ge quantum dots (QDs) for photonic light-emitting devices is reviewed, with a focus on ion implantation as a synthetic tool. Light emissions from Si and Ge QDs are compared with emissions from other optically active centers, such as defects in silicon oxide and other thin film materials, as well as rare-earth light emitters. Detection of light in silicon photonics is performed via the integration of germanium and other elements into detector structures, which can also be achieved by ion implantation. Novel techniques to grow SiGe- and SiGeSn-on-

📒 Our paper on plasma staging of intense ion beams was published in Physical Review Research! https://lnkd.in/gppkfFQ4 Titled “Laser-plasma ion beam booster based on hollow-channel magnetic vortex acceleration,” we propose and demonstrate a novel technique for boosting the energy of intense ion beams from existing, non-relativistic sources to the relativistic regime using a hollow-channel laser-plasma device. We ran first-principle 3D simulations to study the robust properties and tolerances of our concept. 🔬 Scientific Achievement: Our team has successfully shown that high-charge ion beams can be energy boosted (staged) in self-consistent numerical simulations with #WarpX while maintaining critical beam quality parameters. Our approach utilizes a plasma-based near-critical density target. 🌟 Significance and Impact: High-intensity ion beams hold promise for various applications, including future-generation hadron colliders, neutrino factories, fusion energy drivers, radiotherapy, secondary radiation sources for materials science and security applications, nuclear physics, and radiation hardening of spacecraft. Our technique is robust enough for experimental realizations in existing and near-term laser facilities and could advance the impact of laser-plasma interaction (LPI) sources by increasing beam energy to meet the demanding requirements of these applications. 🧪 Research Details: Utilizing the magnetic vortex acceleration (MVA) mechanism, we have proposed a multi-stage approach to boost proton beam energies incrementally. Our self-consistent 3D #WarpX simulations have demonstrated significant energy boosts while preserving key beam quality parameters such as charge, energy spread, and transverse normalized emittance, paving the way for future scientific and practical applications. This research was executed by our team of Berkeley Lab ATAP Division researchers: Marco Garten, PhD, Stepan Bulanov, Sahel Hakimi, Lieselotte Obst-Huebl, Chad Mitchell, Carl Schroeder, Eric Esarey, Cameron G.

#Runway electron beams are a big danger for #ITER and other high current #tokamak devices. Such relativistic electrons can arise in the course of a major #disruption, which terminates a #plasma discharge in an uncontrolled way and can lead to localized massive heat loads onto material structures. Vinodh Kumar Bandaru, now assistant professor in India and previously postdoctoral researcher at Max-Planck-Institut für Plasmaphysik - IPP with a EUROfusion researcher grant and an implementing agreement with ITER Organization, studied extensively how a beam of runaway electrons is lost to the material walls. These are first of a kind non-linear predictive 3D simulations. After a thermal quench, i.e., the loss of thermal confinement during a major disruption, the formation of a beam of highly energetic "runaway" electrons can occur, which vertically drifts towards the material structures until strong magneto-hydrodynamic plasma instabilities set in and distribute the relativistic particles onto the walls. Such an event carries a high risk of damage, such that research is very active towards mitigation of runaway electron beam formation on one hand and to the tailoring of these "termination events" into a more benign form with less localized heat loads on the other hand. The work by Vinodh opens completely new possibilities for predicting how the situation in future tokamak devices will be. This is so important that a whole series of follow-up activities by the #JOREK code community and by our collaborators are already on the way to find out more about the precise heat deposition onto the 3D wall structures and the influence of background plasma parameters in ITER and other machines. A satellite meeting at the plasma physics conference of the European Physical Society this summer will cover the associated damage of material structures (https://lnkd.in/ephN-XFa). Vinodh's article with the 3D ITER studies was just accepted for publication in the journal Nuclear Fusion: https://lnkd.in/e7ME7XAU

The nitrogen-vacancy (NV) center in diamond, a type of #qubit, is useful for #quantum sensing and communication. The NV center itself has many desirable properties, and the surrounding nuclear and electronic spins within the diamond can also be used for quantum information processing.   🔗 https://lnkd.in/gRQzYuCm   However, current methods for creating NV centers in diamond result in their being randomly positioned, limiting the technology's potential for integration with other systems.   With support from Q-NEXT, researchers at the University of Chicago and Argonne National Laboratory used theoretical calculations to optimize the creation of the spins surrounding the NV center. By analyzing coherence data, they identified trends in how different growth variables affect the properties of NV centers. They also developed a method to estimate the characteristics of a sample based on measurements of the NV center's coherence time.   The group’s methods can be applied not only to NV centers but also to other qubit platforms. Their work is published in American Physical Society's Phys Rev Materials.   Learn more: https://lnkd.in/gRQzYuCm   Pritzker School of Molecular Engineering at the University of Chicago UChicago Physics University of Chicago Department of Chemistry   #qnextresearch #quantummaterials #quantumscience #quantumengineering #quantuminformationscience #quantumsensing #quantumcommunication

🔋 Advancing the understanding of Lithium-Ion Batteries on a molecular level🔋 Excited to share our latest research published in the Journal of Physical Chemistry C https://lnkd.in/edg6qzWP Our team of scientists at the Massachusetts Institute of Technology and NASA - National Aeronautics and Space Administration has been working on enhancing the power of lithium-ion batteries using advanced molecular dynamics simulations. We tracked the energetics of lithium-ions as they move from the bulk electrolyte to the cathode (LCO) interface, and revealed both the driving forces and the barriers along the path. At a finite surface coverage of lithium ions, we found out the driving force for adsorption becomes zero, making the lithium-ion transport to interface dependent solely on the thermodynamic barrier. 🔍 Why does this matter? Our findings reveal that the way ions interact and move at the interface can be fine-tuned, paving the way for more efficient and powerful lithium-ion batteries. This study enhances our understanding of battery chemistry and could motivate further works and innovations in electrolyte and interface engineering in energy storage devices.
