A General and Efficient Framework for the Rapid Design of Miniaturized, Wideband, and High‐Bit RIS

Advanced Electronic Materials, EarlyView.
A general and efficient framework is proposed for the rapid design of high‐performance reconfigurable intelligent surfaces (RISs). This framework integrates advanced antenna design techniques and incorporates various load types, quantities, and values to achieve the design of high‐performance RISs.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Metal–Insulator–Insulator–Metal (MIIM) Ag/SnO2/Al2O3/Ag Diodes Fabricated by Ultraprecise Dispensing and Atomic Layer Deposition

Advanced Electronic Materials, EarlyView.
This study introduces a new method for fabricating MIIM diodes using ultra‐precise dispensing printing techniques combined with ALD. Thus, it provides a practical alternative to traditional lithography. The fabricated diode, with a contact area of 5.4 µm × 4.0 µm exhibits a tunneling current in the microampere range, a zero‐bias responsivity of −1.31 A/

High‐Speed Flexible Schottky Diodes Based on Carbon Nanotubes

Advanced Electronic Materials, EarlyView.
We demonstrate a flexible Schottky diode based on carbon nanotube network thin film, and the devices are fabricated via a low‐temperature process on a PI substrate, which exhibits excellent radio‐frequency characteristics, with a high responsivity 6 A/W at zero bias, a high intrinsic cut‐off frequency reaching 153 GHz, and an extrinsic cut‐off ...

Sustainability Strategies in the Cocoa‐Chocolate Value Chain: An Analysis Using Stakeholder Theory, Global Value Chain Theory, and Resource Dependence Theory

Agribusiness, EarlyView.
ABSTRACT The cocoa‐chocolate value chain faces significant environmental and social challenges, driving firms to adopt sustainability strategies ranging from individual practices to third‐party certifications. This study investigates the factors associated with these strategies by analyzing 304 cocoa‐chocolate companies using firm‐level data from the ...
