Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

open access: yesAdvanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

Group-tacit knowledge and organisational effectiveness: analysis of effects using a mixed method approach

open access: yesBusiness: Theory and Practice, 2018
Considering that most part of organisational operations depend on group effectiveness, yet there is scarcely any empirical study on the interactions between group-tacit knowledge and organisational effectiveness. In order to overcome this gap, this study

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

open access: yesAdvanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...

The social representation of telecommunications [PDF]

open access: yesPersonal and Ubiquitous Computing, 2007
For a long time now sociologists have spoken of the domestication of information and communication technologies (ICTs) to indicate their process of integration in everyday life. In this paper, we wish to deal with a crucial aspect of this process, which is the domestication of ICTs at the socio-cognitive level.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Coupling of Er3+ ions and Plasmonic Modes in Vertical Nanocavities for Spectral Broadening in Telecom Bands

open access: yesAdvanced Materials Technologies, EarlyView.
Left: Illustration of the glass & nanostructures system and the NIR emission at 1.5 µm, where the colored spheres represent the Er3+ ions within the doped glass. Right: Representation of the Stark splitting of the 4I13/2 and 4I15/2 manifolds of the Er3+, illustrating how the plasmonic modes facilitate the emission from the broader Stark manifold ...

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites

open access: yesAdvanced Optical Materials, EarlyView.
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.
