Scalable MoS₂/Si Photodiode Arrays From Roll-to-Roll Mechanical Exfoliation. [PDF]

Adv Sci (Weinh)
A dry roll‐to‐roll route transforms mechanically exfoliated MoS2 flake networks into silicon‐integrated photodiode arrays. The MoS2/Si junctions generate photovoltaic output without applied bias, allowing illuminated pixels to locate light spots and reconstruct simple images.
