We report on the intrinsic optoelectronic response of high-quality dual-gated monolayer and bilayer graphene p-n junction devices. Local laser excitation (of wavelength 850 nanometers) at the p-n interface leads to striking six-fold photovoltage patterns as a function of bottom- and top-gate voltages. Though the response speed is slower than pure graphene photodetectors with a response time in the picosecond level, the response time and decay time are still shorter than the nanostructured disordered graphene photodetectors 5,33,36 in which the response speed is around hundreds of seconds caused by the defect/edge scatterings and recombinations. exploit this synergy and provide the ﬁrst direct experimental demonstration of phase modulation in mid-IR using graphene-integrated plasmonic metasurfaces. The technological rationale for using graphene as an electro-optic material comes from the subnanosecond electric response of its optical conductivity to ﬁeld-eﬀect gating.8 Graphene- Jul 13, 2011 · Here, we present measurements of the intrinsic response time of metal–graphene–metal photodetectors with monolayer graphene using an optical correlation technique with ultrashort laser pulses. We obtain a response time of 2.1 ps that is mainly given by the short lifetime of the photogenerated carriers.
