🌟 Exciting News! 🌟 I'm thrilled to share our latest research paper, "Unveiling Excitons in Two-Dimensional Pnictogens." This study delves into the optical, electronic, vibrational, and excitonic properties of four 2D pnictogen materials—nitrogenene, phosphorene, arsenene, and antimonene. By using density functional theory calculations and the Bethe–Salpeter equation, we discovered: 🔬 Indirect gaps with significant exciton binding energies 🔬 Isotropic behavior under circular light polarization 🔬 Anisotropic behavior under linear polarization within the visible solar spectrum (except for nitrogenene) 🔬 Raman frequency red-shifts in heavier pnictogen atoms, consistent with experimental observations 🔬 Intense quasi-particle effects influencing the linear optical response These findings highlight the immense potential of these monolayers for solar energy harvesting and advanced optoelectronic device applications and open new research possibilities in our field. Join us in exploring how these innovative materials can pave the way for the next generation of optoelectronic technologies. The paper is available here https://lnkd.in/eERefS3J, and it's open access. Special thanks to our team, who made this possible: Marcos R. Guassi, Rafael Besse, Maurício Piotrowski, Celso Ricardo Rêgo, Diego Guedes-Sobrinho, Andréia Luisa da Rosa, and Alexandre Cavalheiro Dias. #Simstack #Optoelectronics #SolarEnergy #Nanotechnology #Pnictogens #Excitons #MaterialsScience #Wantibexos

It is my pleasure to share our recent research article titled "Inverse Opal Optical Tamm State for Sensing Applications" has been published in the Journal of Photonics and Nanostructures - Fundamentals and Applications. In this work, we explore the excitation of optical Tamm states in inverse opal-based 3D photonic crystals, where the fabrication process avoids the use of corrosive chemicals. Upon infiltration of non-reactive solvents like methanol and ethanol into the IO, we observed a significant shift in the optical Tamm state, consistent with our simulations. These results highlight the potential of IO-based OTS as an effective sensing tool. This work would not have been possible without the guidance of my supervisors, Dr. Kapil Debnath and Dr. Shivakiran Bhaktha B.N., and the invaluable contributions of our collaborator, Dr. Andrea Chiappini.

We have recently celebrated a very special anniversary. A little over 20 years ago, Science magazine published a curious paper entitled: "Electric Field Effect in Atomically Thin Carbon Films", authored, among others, by Andre Geim and Konstantin Novoselov. The two scientists went on to win a #Nobel Prize just 6 years later, awarded for "groundbreaking experiments regarding the two-dimensional material graphene". Back then, the term #graphene, which is now ubitoqous, was not known and the whole world of opportunities offered by the completely new class of two-dimensional materials was just opening up. As the scientific world celebrates the beginning of graphene's third decade, we are working hard to turn its promise into reality. You can find that very first paper here: https://lnkd.in/dyFy-Y9B

**The Hidden World of Quasi-Crystals: A New Frontier in Material Science** Quasi-crystals, first discovered in 1982 by Dan Shechtman, challenge traditional notions of symmetry in materials science. Unlike regular crystals, which repeat patterns periodically, quasi-crystals exhibit a form of order that is non-repeating yet highly structured. This phenomenon allows for unique properties such as low thermal conductivity and high structural stability. Recent research reveals their potential applications in creating more efficient energy storage systems and advanced coatings. With ongoing studies exploring their role in biomaterials and photonics, quasi-crystals are positioning themselves as a groundbreaking component in the next generation of material science. #MaterialScience #QuasiCrystals #Innovation

New animated cover design inspired by Eli Zysman-Colman and Malte Gather's research into biluminescent materials! Their latest scientific paper explores the properties of nitrogen-containing indolocarbazoles (NICz) and their unique ability to emit light in two different ways simultaneously: biluminescence! Here are some highlights from the paper: ⏣ Discussion of the remarkable biluminescent properties of NICz compounds, and their potential applications in various fields ⏣ Discovery of a novel phenomenon in NICz compounds, showing for the first time in organic emitters multi-resonant thermally activated delayed fluorescence (MR-TADF) combined with room temperature phosphorescence (RTP). ⏣ Valuable insights into the photophysical properties of NICz compounds, a first step toward innovative applications in sensing, optoelectronics and beyond.

We are excited to announce our recent publication, which proposes one key mechanism affecting the defect density in the active region of III-nitride-based light emitters. The manuscript provides evidences for point defect diffusion, and hence how to control the defect density in GaInN/GaN quantum wells by using proper growth conditions. Therefore, it offers a new perspective on the reduction of point defects, allowing further development and design of light-emitting nanostructures with higher efficiency and reliability. Additionally, it has the potential to save natural resources and energy, thereby making optoelectronics a more sustainable business and environment. Although our main focus is on light emitters, in principle, technologies such as GaN-based power devices could also benefit from lower point defect density.
