Advanced Science, EarlyView.BaTiO3‐based polymorphic relaxor ferroelectrics are engineered by mesoscopically chemical homogeneity, constructing diversified nanodomain architectures with similar multiple local symmetries but different nanodomain scales in diverse grains. Ex‐/In situ multiscale structure analysis indicates that a relatively continuous polarization switching with ...

Electric Field‐Driven Conformational Changes in Molecular Memristor and Synaptic Behavior
Advanced Science, EarlyView.Self‐assembled monolayers (SAMs) based molecular device is used for the emulation of synaptic functions. The device operates with a novel switching mechanism via incoherent charge transport, inducing conformational changes. With a low energy consumption (8.0 pJ µm−2), the system shows promise for neuromorphic computing, offering potential in low‐energy,

Advanced Science, EarlyView.The bonding hierarchy in X6Re6S8I8 (X = Rb, Cs) promotes phonon localization, generating extensive discrete phonon flat bands that redefine the lower bounds of lattice thermal conductivity in crystals. Abstract Within the unified theoretical framework for thermal transport, the inherent interplay between coherent tunneling and propagative phonon ...

An Electrode Design Strategy to Minimize Ferroelectric Imprint Effect
Advanced Science, EarlyView.A tunable electrode design using La0.7Sr0.3MnO3 enables precise modulation of ferroelectric imprint through oxygen pressure–controlled work function engineering. By applying this strategy to both perovskite and fluorite systems, the built‐in field is effectively suppressed, enabling low‐voltage, high‐endurance ferroelectric devices, including Fe‐FETs ...
