File List:
- fig1b.txt: two column text file with experimental Raman spectra of a graphene mononlayer on Fe:LiNbO3. The first column corresponds to the Raman shift (1/cm) and the second column to number of counts.
- fig2.txt: two column text file with experimental resistance measurements of graphene/Fe:LiNbO3 device under illumination. First colum corresponds to time (seconds) and the second column to resistance (ohms).
- fig3a.txt: Resistance measurements of graphene/Fe:LiNbO3 device under illumination for graphene channels of varying length. First array corresponds to measured data points for 4 illumination conditions where the first column are graphene channel lengths (microns), while second, third, and fourth columns correspond to resistance values at illumination doses of; 0, 1.8, 3.6, and 5.4 J/cm2 respectively. The second array contains linear fits to the datasets, where the first column corresponds to distance (microns) while the second, third, and fourth columns correspond to resistance values at illumination doses of; 0, 1.8, 3.6, and 5.4 J/cm2 respectively.
- fig3b.txt: Resistivity values of graphene/Fe:LiNbO3 device as a function of fluence. The first array contains experimental data points averaged from 3 data sets; the first column corresponds to fluence (mJ/cm2), the second column contains resistivity values (Ohms/sq), and the third colum contains uncertainty values for error bars. The second array contains X and Y values (first and second column respectively) for the fitted resistivity saturation value. The third array contains X and Y values (first and second column respectively) for the fitted resistivity saturation time (to reach 1/e of maximum resistivity). The fourth array contains contains X and Y values (first and second column respectively) for the fitted exponential function to the experimental data points.
- figS1.txt: Resistivity values for 3 repeat measurments on the graphene/Fe:LiNbO3 device as a function of fluence. the first, second, and third array contain measured values of the three illumination cycles, where the first column corresponds to the offset fluence dose (each cycle delivers a total of 18000 mJ/cm2), the second column corresponds to measured data points, and the third column corresponds to error bar values. The second array contains values for the fitted exponential function, where the first column contains fluence values, and the second column contains resistivity values for the first cycle. The third and fourth columns contain fluence and resistivity values for the second cycle, and the fifth and sixth columns contain fluence and resistivity values for the third cycle.
