Color weakness in congenital color perception deficiency of various degrees
Background: The prevalence of congenital color vision defects (CCVD) is reported to be approximately 8% in males and 0.5% in females, and, therefore, the use of optimal tests capable of diagnosing these defects early and accurately, and with all the ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
