Spectral Tuning of Hyperbolic Shear Polaritons in Monoclinic Gallium Oxide via Isotopic Substitution

Advanced Materials, EarlyView.
Spectral tuning of highly directional hyperbolic shear polaritons is realized via isotopic substitution of 16O to 18O in monoclinic β$\beta$‐phase gallium oxide. A red‐shift of almost 40 cm−1 is experimentally demonstrated with near‐field imaging, corroborated by the permittivity change extracted from far‐field experiments and density functional theory.

Peptide‐Induced Ferroelectricity in Charge‐Transfer Supramolecular Materials

Advanced Materials, EarlyView.
Bio‐inspired supramolecular charge‐transfer amphiphiles self‐assemble into nanoribbons in water, where peptide chirality‐induced symmetry breaking generates robust ferroelectricity across multiple systems. These water‐processable organic ferroelectrics also enhance neuronal outgrowth and electrophysiological maturity, offering a versatile strategy for ...

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Benchmarking Organic Photodiodes at the Noise Floor

Advanced Optical Materials, EarlyView.
A precise measurement framework based on a calibrated, ultra‐low‐noise automated setup with open‐source Python scripts enables accurate benchmarking of photodiodes. The unique combination of time‐dependent current measurement under dark conditions, followed by continuous‐wave faint illumination, facilitates reliable extraction of photocurrent near ...
