Data for the manuscript "Fermi-Level Modulation in Graphene Sensors Revealed by Voltage-Dependent Raman Spectroscopy and 3D Waterfall Response Mapping"

The dataset contains experimental Raman spectroscopy and electrical noise measurements of graphene sensors acquired under different source–drain bias voltages and external chemical and optical stimuli. It includes voltage-dependent Raman spectra, spatial Raman maps of characteristic graphene vibrational bands, and time–frequency data used to generate 3D waterfall plots of sensor responses to near-infrared illumination, acetone, and isopropyl alcohol vapors. The dataset also provides experimental setup illustrations and supporting figures associated with the manuscript "Fermi-Level Modulation in Graphene Sensors Revealed by Voltage-Dependent Raman Spectroscopy and 3D Waterfall Response Mapping."
