Query: Gate-tunable van der Waals heterostructure for reconfigurable neural
  network vision sensor   Early processing of visual information takes place in the human retina.
Mimicking neurobiological structures and functionalities of the retina provide
a promising pathway to achieving vision sensor with highly efficient image
processing. Here, we demonstrate a prototype vision sensor that operates via
the gate-tunable positive and negative photoresponses of the van der Waals
(vdW) vertical heterostructures. The sensor emulates not only the
neurobiological functionalities of bipolar cells and photoreceptors but also
the unique synaptic connectivity between bipolar cells and photoreceptors. By
tuning gate voltage for each pixel, we achieve reconfigurable vision sensor for
simultaneously image sensing and processing. Furthermore, our prototype vision
sensor itself can be trained to classify the input images, via updating the
gate voltages applied individually to each pixel in the sensor. Our work
indicates that vdW vertical heterostructures offer a promising platform for the
development of neural network vision sensor.
