Abstract

The invention relates to a light-emitting electrochemical artificial synapse with a photoelectric signal parallel output function. The light-emitting electrochemical artificial synapse comprises a substrate, a bottom electrode, a light-emitting active layer and a top electrode which are sequentially arranged from bottom to top, the light-emitting active layer is composed of a light-emitting material, an ion transmission matrix and a lithium salt, when continuous voltage pulses are input, the light-emitting material and the ion transmission matrix in the active layer are subjected to an electrochemical oxidation-reduction reaction, the conductivity of the device is gradually increased, and then synaptic current is gradually increased; meanwhile, along with the increase of electron and hole injection, the transient electroluminescence intensity is gradually enhanced. The intensity of the output optical signal and the intensity of the output electric signal can serve as synaptic weights at the same time, the method can be used for constructing a photoelectric hybrid artificial neural network, and a brand new feasible scheme is provided for achieving a neural morphology calculation system with light and electricity as media at the same time.

Description

technical field [0001] The invention belongs to the technical field of artificial synapse devices, and in particular relates to a luminescent electrochemical artificial synapse with a parallel output function of photoelectric signals and a method thereof. Background technique [0002] With the popularization of the fifth generation wireless system (5G), people generate a large amount of data traffic in daily life, including text, image, audio and video files, which accelerates the development of the era of big data. Faced with the explosive growth of data information, computers based on the traditional von Neumann framework have been unable to handle complex tasks (such as digital image analysis, speech recognition and intelligent navigation) with low power consumption, while the human brain nervous system can simultaneously serve as Processor and memory to learn, memorize and calculate large amounts of external information in an efficient and highly parallel manner. The sy...
