Abstract—We present the conductometric behavior of a single
atomic carbon nanostructure (graphene) that could be promising
to infrared optoelectronic applications. A graphene
nanomanipulation system with focused infrared laser source for
optoelectronic property characterizations is implemented. The
feasibility of mechanical and electrical probing manipulations on
two-dimensional thin film nanostructures is studied. Using this
system, we revealed the infrared optoelectronic properties of
mono- and multilayer graphene. The obtained optoelectronic
parameters are compared to the single- and multi-walled
nanotubes. A graphene infrared sensor is prototyped by direct
writing of electrodes using gold nanoink fountain-pen method
and is analyzed by electrical probing. Results show that graphene
could be a promising building block for thin film optoelectronic
devices.
