Halide Perovskite Memristor Crossbar Arrays for Low Voltage in Memory Computing

open access: yesAdvanced Materials Interfaces, EarlyView.
From early devices to centimeter‐scale crossbars, halide‐perovskite memristors now deliver ultra‐low‐energy, multilevel switching. Yet ion migration, device variability, and sneak currents hinder scaling. Advances in self‐rectifying junctions, nonlinear interfaces, bias maps, and hybrid oxides enhance array stability.

Multimaterial Microrobots for pH Sensing Fabricated Using Sequential 3D and 4D Printing with Automated Alignment

open access: yesAdvanced Materials Technologies, EarlyView.
This work proposes the use of multimaterial microrobots for pH sensing. The microrobots consist of a hard polymer backbone and 4D printed sensing elements made of a pH‐responsive hydrogel. The swelling response, reusability, and high mobility of the microrobots make them promising tools for pH sensing at the micro scale.

Polar Indirect Valley as a Limiting Factor for Radiative Efficiency in Gold‐Based Mixed‐Valence Double Perovskites

open access: yesAdvanced Optical Materials, EarlyView.
This work addresses a common issue in many double perovskites: their weak luminescence. Using the example of promising infrared‐bandgap mixed‐valence gold halide double perovskites, it demonstrates strong polar electron‐phonon coupling. Temperature‐dependent spectroscopy reveals that bright polarons are favored at low temperature, while a dark low ...
