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 ...

KELLEY-MORSE PLUS TYPES OF WELL ORDER IS NOT A CONSERVATIVE EXTENSION OF KELLEY-MORSE

open access: yes, 1994
Assuming the consistency of ZF + ''There is an inaccessible number of inaccessibles'', we prove that Kelley Morse theory plus types is not a conservative extension of Kelley-Morse ...

Strengthened Interfacial Coupling Between Self‐Assembled Monolayers and Bulk Heterojunctions Enables Thermally Stable Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Molecularly engineered self‐assembled monolayers (SAMs) featuring extended conjugated terminals facilitate superior interfacial coupling with the organic solar cell active layer. By physically anchoring the local morphology, this design suppresses thermal degradation, allowing devices to operate at 85°C for 150 h before degrading to 90% of their ...

A linear conservative extension of Zermelo-Fraenkel set theory

open access: yes, 1995
In this paper, we develop the system LZF of set theory with the unrestricted comprehension in full linear logic and show that LZF is a conservative extension of ZF 0 i.e., the Zermelo-Fraenkel set theory without the axiom of regularity.

Bias‐Field Free Single‐Frequency CW‐ODMR of Nitrogen‐Vacancy Centers in Diamond for the Detection of Transient Electrical Signals

open access: yesAdvanced Materials Interfaces, EarlyView.
Simplified quantum sensing technique for the detection of short electrical signals occurring in neuronal signaling or bioinspired technologies. We demonstrate a single frequency continuous‐wave optically detected magnetic resonance (CW‐ODMR) approach to sense signals that can be as short as 0.2 ms.

Conservative extensions, interpretations between theories and all that! [PDF]

open access: yes, 1997
About twenty years ago together with a group of collaborators, some conjectures were developed about the fundamental principles of a theory of specification. These principles included the use of interpretations between theories to underpin the concept of representation and parameterisation, conservative extensions to underpin the concept of modularity ...

Calcul de conséquences pour le test d'extension conservative dans un système pair-à-pair [PDF]

open access: yes, 2008
National audienceDans un système d'inférence pair-à-pair (P2PIS), un pair étend sa base de connaissances (KB) avec celle des autres pairs afin d'utiliser leurs connaissances pour répondre aux requêtes qui lui sont posées. Toutefois, l'ex tension d'une KB

Tunable Extraordinary Optical Transmission in the Long‐Wavelength Infrared Range Using Electrostatic MEMS Actuation

open access: yesAdvanced Materials Technologies, EarlyView.
A MEMS‐integrated metamaterial filter enables continuous, low‐voltage spectral tuning in the long‐wavelength infrared (LWIR). The device employs extraordinary optical transmission in a dual suspended metasurface stack, where electrostatic actuation precisely controls the intermembrane air gap.

On‐Chip Saturated Absorption of CO2 in a Silicon‐on‐Sapphire Waveguide

open access: yesAdvanced Optical Materials, EarlyView.
We demonstrate the first saturated absorption of a molecular gas on a planar photonic chip. By coupling carbon dioxide with the tightly confined light of a silicon‐on‐sapphire waveguide, we achieve optical saturation using only milliwatt powers. This breakthrough provides a practical, low‐power foundation for creating ultra‐compact mid‐infrared ...

Waveguide Geometry–Driven Trade‐Offs in Resonant Cavity Sensor Performance

open access: yesAdvanced Optical Materials, EarlyView.
Waveguide geometry governs the interplay between sensitivity, intrinsic Q‐factor, and wavelength noise in silicon nitride resonant sensors. Contrary to intuition, higher sensitivity does not ensure superior performance. Low‐noise, high‐Q ridge resonators achieve the lowest detection limits, revealing that detection is ultimately constrained by noise ...
