Nanowerk  November 18, 2020 Realization of a single imaging unit with a combination of in‐built memory and signal processing capability is imperative to deploy efficient brain‐like vision systems. An international team of researchers (Australia, USA – Colorado State University, UC Berkeley, China) has designed a neuromorphic imaging element based on a fully light‐modulated 2D semiconductor in a simple reconfigurable phototransistor structure. This standalone device exhibits inherent characteristics that enable neuromorphic image pre‐processing and recognition. They exploited the unique photo response induced by oxidation‐related defects in 2D black phosphorus to achieve visual memory, wavelength‐selective multibit programming, and erasing functions, which allow […]
