Identification and thermal healing of focused ion beam-induced defects in GaN using off-axis electron holography
Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Yi Wang
Thermal healing of focused ion beam-implanted defects in GaN is investigated by off-axis electron holography in TEM. The data reveal that healing starts at temperatures as low as about 250 degrees C. The healing processes result in an irreversible transiti ...
Bristol2024Memristive Control of Plasmon-Mediated Nonlinear Photoluminescence in Au Nanowires
Nonlinear photoluminescence (N-PL) is a broadband photon emission arising from a nonequilibrium heated electron distribution generated at the surface of metallic nanostructures by ultrafast pulsed laser illumination. N-PL is sensitive to surface morphology ...
Amer Chemical Soc2024Dataset to accompany publication "Quantum-mechanical effects in photoluminescence from thin crystalline gold films"
Giulia Tagliabue, Fateme Kiani Shahvandi, Alan Richard Bowman, Theodoros Tsoulos
This dataset accompanies the publication "Quantum-mechanical effects in photoluminescence from thin crystalline gold films" published in Light: Science & Applications (https://doi.org/10.1038/s41377-024-01408-2). The data can be used to reproduce plots 1-4 ...
Zenodo2024Data-Intensive Exploration of the Photoelectrochemical Responses of Main-Group Metal Sulfides
Materials that efficiently promote the thermodynamically uphill water-splitting reaction under solar illumination are essential for generating carbon-free ("green") hydrogen. Mapping out the combinatorial space of potential photocatalysts for this reaction ...
Amer Chemical Soc2024Quantum-mechanical effects in photoluminescence from thin crystalline gold films
Giulia Tagliabue, Fateme Kiani Shahvandi, Alan Richard Bowman, Theodoros Tsoulos
Luminescence constitutes a unique source of insight into hot carrier processes in metals, including those in plasmonic nanostructures used for sensing and energy applications. However, being weak in nature, metal luminescence remains poorly understood, its ...
2024Doping Engineering for PDP Optimization in SPADs Implemented in 55-nm BCD Process
Edoardo Charbon, Claudio Bruschini, Myung Jae Lee, Feng Liu
We introduce a new family of single-photon avalanche diodes (SPADs) with enhanced depletion regions in a 55-nm Bipolar-CMOS-DMOS (BCD) technology. We demonstrate how to systematically engineer doping profiles in the main junction and in deep p-well layers ...
Piscataway2024High-throughput screening of Weyl semimetals
Nicola Marzari, Davide Campi, Davide Grassano
Topological Weyl semimetals represent a novel class of nontrivial materials, where band crossings with linear dispersions take place at generic momenta across reciprocal space. These crossings give rise to low -energy properties akin to those of Weyl fermi ...
College Pk2024Electrical and Optical Manifestations of Flat Band Physics in Van der Waals Materials
The scientific progress is significantly transforming contemporary society with the introduction and widespread application of technologies like artificial intelligence and quantum computing. Despite their profound impact, these technologies necessitate en ...
EPFL2024Exciton migration in two-dimensional materials
Excitons play an essential role in the optical response of two-dimensional materials. These are bound states showing up in the band gaps of many-body systems and are conceived as quasiparticles formed by an electron and a hole. By performing real-time simu ...
Nature Portfolio2024Towards Scalable Electronics: Synthetic 2D Materials for Large-Area 2D Circuit Integration
In the past decades, a significant increase of the transistor density on a chip has led to exponential growth in computational power driven by Moore's law. To overcome the bottleneck of traditional von-Neumann architecture in computational efficiency, effo ...
