description: Dataset associated with the manuscript "Graphene-perovskite fibre photodetectors" Details of files: - Fig1d a spreadsheet containing raw data, with the y-axis representing current and the x-axis representing voltage as a function of the number of rolling cycles. In the Excel sheet, columns ranging from approximately -1 to 1 V represent the applied bias, while the rest correspond to the measured current values. - Fig2 a spreadsheet containing raw data for the Raman spectra of CVD SLG on Cu and rolled graphene for different numbers of rolled layers. The columns, ranging mainly from 3500 to 1000, represent wavenumbers, while the corresponding Raman intensity values are provided for different layers of rolled SLG. - Fig3 a spreadsheet containing raw data for Raman spectroscopy and the analysis of average values and standard deviations of: I(2D)/I(G), A(2D)/A(G), FWHM(G), Pos(G), FWHM(2D), Pos(2D), I(D)/I(G), and Pos(2D) as a function of Pos(G).
