Two‐Stage Bipolaron Formation in Molecularly Doped Conjugated Polymers
Advanced Materials, EarlyView.This work investigates bipolaron formation in 2,3,5,6‐tetrafluoro‐7,7,8,8‐tetracyanoquinodimethane (F4TCNQ)‐doped conjugated polymer P(g32T‐T) films with glycol sidechains at two stages of both low and high doping levels. At the early stage, bipolarons mainly form from double doping, enhancing structural ordering, and carrier transport.

Dynamic and Reconfigurable Acoustic Fields Enabled by Morphing Fluidic Holographic Lenses
Advanced Materials Technologies, EarlyView.Real‐time reconfiguration of the acoustic field is achieved using fluidic holographic lenses that dynamically morph their structure via controlled volume changes. This compact, programmable approach eliminates the need for active elements like phased arrays, enabling high‐resolution, adaptive wavefront control with enhanced flexibility for diverse ...

Enhanced THz Emission From Ultrathin Ta/Fe/Pt Spintronic Trilayers
Advanced Optical Materials, EarlyView.Ultrathin Ta/Fe/Pt spintronic trilayers on MgO(100) substrates generate intense terahertz (THz) emission under femtosecond laser pulse excitation. Constructive interference of the emitted THz waves from Ta and Pt layers is maximized through crystallographic engineering of the Ta layer into a high‐resistivity fcc phase and optimization of the trilayer ...
