Scalable Patterning of Organic Electrochemical Transistors for Logic Gates and Neuromorphic Computing

ABSTRACT Organic electrochemical transistors (OECTs) are promising building blocks for bioelectronics owing to their efficient ion–electron coupling, soft‐material compatibility and high transconductance. However, their large off‐state currents and poor scalability have so far li...

Optical phased array LiDAR chips towards polarization-resolved 4D sensing

Optical phased array (OPA)-based LiDAR technology provides high-speed, solid-state sensing for autonomous vehicles, robotics, and aerial systems. However, current OPA-based LiDAR platforms lack the ability to accurately recognize and classify materials, limiting their effectivene...

Aromatic Heterocycle Ligands for Perovskite Photovoltaics: Balancing Defect Passivation and Heterostructure Formation

ABSTRACT Inverted perovskite solar cells (PSCs) possess great potential for improving efficiency and operating stability, but parasitic charge recombination at the interfaces still limits their performance. As additives and surface treatment agents, ammonium ligands have been rep...

The Evolution of Metal Halide Perovskite Transistors

ABSTRACT Metal halide perovskites (MHPs) offer a revolutionary pathway for next‐generation field‐effect transistors (FETs) because of their exceptional carrier mobilities and cost‐effective processability. However, their transition to practical electronics is significantly challe...

High‐Performance Laser Engine Enabling Synchronous Chirp Linearization for Wavelength‐Resolved FMCW Photonic Systems

ABSTRACT Integrated frequency‐modulated continuous‐wave (FMCW) photonic devices provide a promising route toward compact, fully solid‐state LiDAR systems. By incorporating passive dispersive structures, wavelength‐resolved FMCW architectures further exploit wavelength as an addit...
