ABSTRACT Conventional spectrometers and polarization‐resolved imagers rely on dispersive optics or filter stacks, significantly limiting their miniaturization and system integration. Herein, a compact perovskite/organic blazed‐grating photodetector that functions as a bias‐encode...

Magnetic-field tuning of quantum phase slips in a macroscopic granular aluminum film
Quantum phase slips (QPSs) fundamentally govern low-temperature dissipation in one-dimensional nanoscale superconductors but remain largely unexplored in macroscopic architectures lacking strict geometric confinement. In this work, the magnetic-field-tuned evolution of the macros...

The Bi2Se3 family is widely regarded as the prototypical three-dimensional topological insulator, which is an ideal platform for investigating topological quantum phenomena such as the quantum anomalous Hall effect and Majorana fermions. Further application requires high-quality...

IMPC of Multiple Precision Motion Systems Subject to Dynamic Coupling and Input Delay
Complex manufacturing processes, such as lithography, frequently depend on the coordinated operation of multiple precision motion systems whose accuracy is typically undermined by three principal limitations: dynamic coupling among the subsystems, input delays within their contro...

ABSTRACT Pulsed laser deposition is known for copying the composition of a target into a thin film. Adding a reactive gas can change the growth process, but the chemistry usually stays close to the target. Using a carbon‑rich environment and a pulsed chlorine source from polyviny...
