摘要

Abstract

To develop artificial intelligence and humanoid robotics

it is crucial to fabricate advanced vision systems with high efficiency and versatility. A key challenge is the functional integration of high-speed photodetectors (PD) and neuromorphic vision sensors (NVS) into a single device

as current studies suffer from complex architectures or fabrication processes. Hence

we propose a universal Microzone Femtosecond Laser Deposition (M-FLD) technique that enables the localized

in situ deposition of zero-dimensional (0D) black phosphorus (BP) nanoparticles onto a two-dimensional (2D) MoS

channel by ablating a micro-scale solid-state target. By M-FLD and h-BN nanomask

we fabricated a spatial asymmetric 0D/2D heterostructure for highly integrated dual-mode optoelectronic device. By changing the direction of

the device can be converted from PD to NVS. Under the PD mode

the device can sense high-frequency optical signals up to 3030 Hz. Under the NVS mode

the device’s optical energy consumption per activity is only 191.2 pJ. Based on the sensing and memory capabilities

the device is simulated for MNIST handwritten digit recognition

achieving an accuracy of up to 96.20%. This work provides a flexible and powerful platform for fabricating complex heterostructures

paving the way for highly integrated and reconfigurable neuromorphic vision systems.
