AI Technical Summary
Existing solar-blind ultraviolet detectors can only serve as sensors and are unable to achieve deep perception and intelligent identification of targets in dynamic and complex environments. They also lack information processing and memory functions, and traditional separate optoelectronic systems cannot meet the needs of intelligent monitoring.
Design a carbon-based van der Waals heterojunction opto-synaptic device, including a light-absorbing substrate layer, an interface functional layer, and an electrode structure. Utilize a diamond substrate, an hBN layer, and a bandgap graphene layer to achieve the regulation and information storage of photogenerated carriers. Modulate the conductivity of the device through an electrostatic field to construct the electrode structure of an opto-memristor or opto-transistor.
It realizes the sensing and memory functions of solar-blind ultraviolet light signals, and can learn and forget under different light intensities and pulse numbers. It has intrinsic solar-blind anti-interference characteristics, and performs signal processing and memory directly at the sensor end, thus promoting the intelligent ultraviolet sensing system that integrates sensing, storage and computing.
