摘要

Abstract

Graphene is a very attractive material for broadband photodetection in hyperspectral imaging and sensing systems. However

its potential use has been hindered by tradeoffs between the responsivity

bandwidth

and operation speed of existing graphene photodetectors. Here

we present engineered photoconductive nanostructures based on gold-patched graphene nano-stripes

which enable simultaneous broadband and ultrafast photodetection with high responsivity. These nanostructures merge the advantages of broadband optical absorption

ultrafast photocarrier transport

and carrier multiplication within graphene nano-stripes with the ultrafast transport of photocarriers to gold patches before recombination. Through this approach

high-responsivity operation is realized without the use of bandwidth-limiting and speed-limiting quantum dots

defect states

or tunneling barriers. We demonstrate high-responsivity photodetection from the visible to infrared regime (0.6 A/W at 0.8 μm and 11.5 A/W at 20 μm)

with operation speeds exceeding 50 GHz. Our results demonstrate improvement of the response times by more than seven orders of magnitude and an increase in bandwidths of one order of magnitude compared to those of higher-responsivity graphene photodetectors based on quantum dots and tunneling barriers.
