Imaging folder: it contains all the pictures and datasets of two leaves acquired in the terahertz frequency range and in the visible. In the Leaf1 subfolder are reported the text files (.dat), the matlab files (.fig), and figures (.jpg) for different backgate voltages of the detector. The NEP*.*.opj are origin files containing the data set relatives to the Noise-equivalent-power in different biasing configuration of the detector; positive forward bias (forward3mv,forward5mv), zero bias(0mV) and negative bias (reverse3mv). The detection.opj file contains the detection measurements obtained by blocking and unblocking the THz light onto the detector, at different back-gate voltages; this set of measurements was acquired on 12/2015. The correct_incorrect_polarization.opj and the forward_reverse_bias.opj are origin files containing the data sets relative to the detection experiments with the correct incident light polarization and incorrect one and in the forward and reverse biasing conditions, respectively. This data set has been acquired on 4/2016. The S11Data.txt are the text set data of the simulated reflectivity from the bow-tie arrays obtained by the Comsol simulations for different graphene conductivity values. These data set are also reported in the S11_data.opj origin file. TDS_resonance.opj and TDS_Map.fig are the origin file containing the measured terahertz reflectivity with a broadband frequency source of the detecting array used for the imaging at different back-gate voltages, and the matlab figure reflectivity map for all the arrays, respectively. The Electrical_sd_characterization.opj contains the electrical characterization of the device; it reports the resistance between source and drain contacts by varying the back-gate voltage and at different forward/reverse biases. These data are also reported in the matlab figure file Electrical_SD.fig. Dirac_point.opj is the origin file containg the source-drain resistance at different back-gate voltages needed in order to identify the graphene Dirac point.
