摘要

Abstract

The development of negative photoconductivity (NPC)-related devices is of great significance for numerous applications

such as optoelectronic detection

neuromorph

ic computing

and optoelectronic synapses. Here

an unusual but interesting NPC phenomenon in the novel cesium cobalt chlorine (Cs

CoCl

) single crystal-based optoelectronic devices is reported

which simultaneously possess volatile resistive switching (RS) memory behavior. Joint experiment−theory characterizations reveal that the NPC behavior is derived from the intrinsic vacancy defects of Cs

CoCl

which could trap photogenerated charge carriers and produce an internal electric field opposite to the applied electric field. Such NPC effect enables an abnormal photodetection performance with a decrease in electrical conductivity to illumination. Also

a large specific detectivity of 2.7 × 10

Jones and broadband NPC detection wavelength from 265 to 780 nm were achieved. In addition to the NPC response

the resulting devices demonstrate a volatile RS performance with a record-low electric field of 5 × 10

V m

−1

. By integrating the characteristics of electric-pulse enhancement from RS and light-pulse depression from NPC

an artificial optoelectronic synapse was successfully demonstrated

and based on the simulation of artificial neural network algorithm

the recognition application of handwritten digital images was realized. These pioneer findings are anticipated to contribute significantly to the practical advancement of metal halides in the fields of in-memory technologies and artificial intelligence.
