Combined Influence of Precursor Source and Solvent Type on Microstructural and Optical Properties of Spin-Coated ZnO Thin Films

Alphonse Déssoudji Gboglo, Mazabalo Baneto, Ognanmi Ako, Abdoul-Razak Ali-Tagba, Bruno Grandidier, Kekeli N’konou

The present work investigates the combined effect of precursor source and solvent on the structural, morphological, and optical properties of ZnO thin films prepared by the spin-coating technique. Three precursor sources (zinc acetate dihydrate, zinc chloride, and zinc nitrate hexahydrate) and four...

Harnessing normal-shear coupling in metabarriers for deep sub-wavelength underwater noise control

Vinícius F Dal Poggetto, Marco Miniaci

Anthropogenic underwater noise poses a significant threat to marine ecosystems, disrupting key biological functions. Common mitigation strategies include enclosing noise sources within acoustic barriers. Current designs include locally resonant absorbers, which offer narrow-band performance, and...

0.53 mΩ.cm 2 /592 V High Breakdown Voltage GaN-on-Sapphire Schottky Diodes Without Edge Termination

Hugo Bouillaud, Beatriz Orfao, Etienne Okada, Yannick Roelens, Malek Zegaoui, Mohammed Zaknoune

In this letter, we report high-performance Pt/GaN quasi-vertical Schottky barrier diodes on sapphire substrate. With a 5 μm drift layer and a highly controlled fabrication process, the devices demonstrate an extremely low on-resistance of 0.53 mΩ.cm² while exhibiting a high breakdown voltage of 592...

Ultralow‐Dispersion Silicon THz Photonic Crystal Interconnects for Multichannel Datalinks

Nikhil Navaratna, Thomas Caiwei Tan, Pascal Szriftgiser, Guillaume Ducournau, Ranjan Singh

All-Silicon (Si) Terahertz (THz) interconnects are a key platform for next-generation on-chip communication, leveraging broadband photonics to connect reconfigurable electronics. Yet their potential remains largely unrealized, due to low reported data rates and a lack of systematic insight into the...

Far-Field Terahertz Spectroscopy of a Subwavelength Single Planar Meta-Atom

Surya Revanth Ayyagari, Simonas Indrišiūnas, Guillaume Ducournau, Vytautas Janonis, Irmantas Kašalynas

Accurate measurements of light-matter interactions at subwavelength scales are critical for advancing nanophotonic and quantum optical technologies. In this paper, we present the far-field terahertz (THz) spectroscopy of a single planar meta-atom of subwavelength dimensions embedded within a square...

Real-Time Evolution of the Mechanical Properties of Flax Stems During Post-Harvest Dew Retting: Towards Objective Retting Assessment

Ali Reda, Lionel Buchaillot, Steve Arscott

Post-harvest field dew retting is a critical stage in flax fibre production because it facilitates the separation of fibre bundles from the surrounding stem tissues. In current agricultural practice, the optimum retting stop-point is still assessed largely using empirical criteria, motivating the...
