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 nanoribbons, which enable simultaneous broadband and ultrafast photodetection with high responsivity. These nanostructures merge the advantages…

Photoexcitation cascade and multiple hot carrier generation in graphene
For many optoelectronic applications, such as photodetection and light harvesting, it is highly desirable to identify materials in which an absorbed photon is efficiently converted to electronic
Photocurrent imaging and efficient photon detection in a graphene transistor.
It is shown that at a certain gate bias, the impact of the metal on the channel potential profile extends into the channel for more than one-third of the total channel length from both source and drain sides; hence, most of the channel is affected by the metal.
Ultrafast collinear scattering and carrier multiplication in graphene.
The mechanisms controlling the ultrafast dynamics, in particular the role of collinear scattering, are identified, which gives rise to Auger processes, including charge multiplication, which is key in photovoltage generation and photodetectors.
