Zero-Bias Visible to Near-Infrared Horizontal p-n-p TiO<sub>2</sub> Nanotubes Doped Monolayer Graphene Photodetector

We present a p-n-p monolayer graphene photodetector doped with titanium dioxide nanotubes for detecting light from visible to near-infrared (405 to 1310 nm) region. The built-in electric field separates the photo-induced electrons and holes to generate photocurrent without bias voltage, which allows...
