Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

Advanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Twisted MoS2 Bilayers as Functional Elements in Memtransistors: Hysteresis, Optical Signatures, and Photocurrent Kinetics

Advanced Electronic Materials, EarlyView.
ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...

Remarkable Electric Field‐Controlled Magnetism in La/Sm Co‐Substituted BiFeO3 Multiferroic Ceramics

Advanced Electronic Materials, EarlyView.
The remarkable electric field‐controlled magnetism (change of Mr reaches up to 62.7%) in La/Sm co‐substituted BiFeO3 ceramics, originating from the electric field‐induced phase transition of Pna21/R3c, is achieved by enhancing the dielectric strength. Moreover, the significant improvement in ferroelectricity is also determined after the electric field ...
