On the Accessibility of Higher‐n Phases in Formamidinium‐Based Ruddlesden‐Popper and Dion–Jacobson Layered Hybrid Perovskites

open access: yesAdvanced Electronic Materials, EarlyView.
We investigate FA‐based layered hybrid perovskites containing aromatic cations for Ruddlesden‐Popper and Dion‐Jacobson phases and explore the effect of Cs+ on the formation of n > 1 phases through a combination of techniques. We exclude the formation of higher (n > 2) phases, even in the presence of Cs+, despite improved photovoltaics, offering a ...

Artificial Cilia for 360° Direction‐Sensitive Acoustic Sensing Through Additive Micromanufacturing

open access: yesAdvanced Electronic Materials, EarlyView.
An artificial cilium using additive micro‐manufacturing technologies for direction‐sensitive acoustic sensing is prepared, including electrospray and 3D micro‐direct ink writing. Two resonances are achieved on a cilium by printing two independent electrode‐to‐electrode interconnect bridges.

Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

open access: yesAdvanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications
