Two-dimensional ambipolar van der Waals heterostructures enabling in-sensor computing for high-accuracy image recognition
文献摘要：
A traditional image recognition system is separately composed of a photodetector and a processing system.The photodetector first detects a target light signal,then converts the detected light signal to an electrical signal,and then transmits it to the com-puting system for recognition[1-3].Unfortunately,the photo-detector generates a large amount of redundant information when detecting a target image,and the redundant information is also transmitted to the processing system,resulting in low image recognition efficiency,high power consumption and high delay[4-6].Photodetectors integrating image processing may solve these bottlenecks.However,lattice strain existing at the interface of traditional semiconductor heterostructures,makes the band-coupling type difficult to be modulated,and the interfacial electric field cannot be flipped[7].Therefore,it is difficult for a traditional semiconductor heterostructure to realize the polarity control of photoresponse,and consequently to simulate in-sensor computing for image recognition.Thus,there is an urgent need to develop novel semiconductor heterostructures with interfacial band-coupling types capable of reversible tran-sition to realize functional integration of photodetection and information processing.
