Protected Chaos in a Topological Lattice

open access: yesAdvanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Self‐Powered UV Dual‐Band Photodetector Based on Cs3BiCl6/GaN Heterojunction for Logical Operation and Encrypted Photo‐Communication

open access: yesAdvanced Science, EarlyView.
Utilizing the special dual‐band absorption characteristics of Cs3BiCl6 and its strong surface‐charge recombination behavior, a self‐powered UV dual‐band photodetector based on Cs3BiCl6/GaN heterojunction is developed. As a result, the photodetector exhibits excellent specific detectivity of 1.23 × 1012 Jones and ultrafast response speed of τr/τf = 28 ...

A Self‐Adaptive Reconfigurable Metasurface for Electromagnetic Wave Sensing and Dynamic Reflection Control

open access: yesAdvanced Science, EarlyView.
Reconfigurable metasurfaces typically require human intervention or complex, resource‐heavy processes. This innovative self‐adaptive metasurface senses an incident wave's direction, adjusting reflection in real‐time using a simple electronics module. It eliminates external controllers, reducing response time, energy consumption, and costs. Applications

An Electrode Design Strategy to Minimize Ferroelectric Imprint Effect

open access: yesAdvanced 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 ...

Mobility‐Lifetime Products in Organic Infrared Photodiodes with Peak Absorption at 1550 nm

open access: yesAdvanced Electronic Materials, EarlyView.
This study analyzes the mobility‐lifetime products in organic infrared photodiodes with different donor‐to‐acceptor ratios to examine charge collection performance. Abstract Infrared photodiodes based on organic semiconductors are promising for low‐cost sensors that operate at room temperature. However, their realization remains hampered by poor device
