Advanced Functional Materials, EarlyView.Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Double diffraction in an atomic gravimeter
, 2009 We demonstrate the realization of a new scheme for cold atom gravimetry based on the use of double diffraction beamsplitters recently demonstrated in \cite{Leveque}, where the use of two retro-reflected Raman beams allows symmetric diffraction in $\pm ...

Probing For New Physics and Detecting non linear vacuum QED effects using gravitational wave interferometer antennas [PDF]
, 2008 Low energy non linear QED effects in vacuum have been predicted since 1936 and have been subject of research for many decades. Two main schemes have been proposed for such a 'first' detection: measurements of ellipticity acquired by a linearly polarized ...

Advanced Functional Materials, EarlyView.This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

Development of a high-performance readout circuit for photoelectric detectors
AIP Advances, 2020 A high-performance readout circuit for photoelectric detectors is developed in this paper to achieve high-speed low-noise image detection. Here, the W/L ratio of the first-stage P-type following transistor is reduced to decrease the parasitic capacitance

Advanced Functional Materials, EarlyView.Multifunctional atomic layer deposited coatings and interface treatments enhance direct solar water splitting on GaAs/GaInP tandem cells. Optimized TiO2/Pt nanoparticle bilayers ensure durability and catalytic efficiency with minimal optical losses, while H2 plasma pretreatments maximize photovoltage and interfacial charge extraction.

Developing a method for modeling, characterizing and mitigating parasitic light sensitivity in global shutter CMOS image sensors [PDF]
, 2021 L’imagerie à haute-vitesse sans distorsions spatiales est devenue cruciale pour une large gamme d’applications comme la vision industrielle, la reconnaissance du mouvement et l’imagerie de la Terre depuis l’espace. La technologie d’imagerie CMOS a donc évolué vers une modalité de prise de vue appelée « snapshot », grâce au développement des Capteurs d ...
