Charge Injection and Transport in an Isoindigo‐Based Polymer Transistor
Advanced Electronic Materials, EarlyView.This study presents the charge injection and transport properties of field‐effect transistors based on an isoindigo‐bithiophene donor‐acceptor polymer semiconductor contacted with thiolated self‐assembled monolayer (SAM)‐functionalized electrodes. Temperature‐dependent contact characteristics are measured and simulated.

Advanced Electronic Materials, EarlyView.A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

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.
