Data for "Inhomogeneities across boron-doped nanocrystalline diamond films"

Electrical transport measurements of the superconducting properties of each sample were taken using a Quantum Design Physical Property Measurement System (PPMS). The PPMS data can be opened using any software that can open ".dat" files. "230929_A_B_D_1uA" corresponds to data from samples A, B and D from the 12 k film. "230929_C_230929B_A" corresponds to data from sample C from the 12 k film and sample A from the 6 k film. "230929B_B_C_D_1uA"  corresponds to samples B, C, D from the 6 k film. These files contain all resistance, temperatures and magnetic fields in seperate labelled columns. In "230929_A_B_D_1uA", the resistance data for samples A, B and D, from the 12 k film, are in the columns titled "Bridge 1 Resistivity (Ohm)",  "Bridge 2 Resistivity (Ohm)" and "Bridge 3 Resistivity (Ohm)", respectively. In "230929_C_230929B_A_1uA" the resistance data for sample C from the 12 k film and sample A from the 6 k film are in the columns titled "Bridge 3 Resistivity (Ohm)" and "Bridge 1 Resistivity (Ohm)", respectively. In "230929B_B_C_D_1uA" the resistance data for samples B, C and D, from the 6 k film, are in the columns titled "Bridge 1 Resistivity (Ohm)",  "Bridge 2 Resistivity (Ohm)" and "Bridge 3 Resistivity (Ohm)", respectively. Since magnetic field data and temperature data are all in the same file, it needs to be seperated manually. Magnetic field data is under the column titled "Magnetic Field (Oe)" and temperature data is under the column titled "Temperature (K)" for all files.

Raman spectroscopy was performed using a 532 nm laser in a Horiba LabRAM HR Evolution equipped with a SynapsePlus Back-Illuminated Deep Depletion (BIDD) CCD. The data is stored in .txt files and each file has the same naming convention - film_sample_532. For example, 230929_A_532 corresponds to sample A from film 230929. 230929 is the '12 k' film and 230229B is the '6 k film. Each file contains two columns, the first corresponds to the Raman shift and the second corresponds to the intensity.

X-ray photoelectron spectroscopy (XPS) was performed on a Thermo Fisher Scientific K–alpha+ spectrometer and analysed in CasaXPS v2.3.26PR1.0. The data is stored in a .vms file and requires the software "CasaXPS" to open. Once opened, the "EDIT MODE" button can be pressed to reveal which sample each piece of data belongs to. The same naming convention is -  film_sample.

A Bruker Dimension Icon atomic force microscope (AFM) was used to capture images of the sample surfaces. The microscope was operated in peak force tapping mode using a ScanAsyst tip. The folder labelled 'AFM' contains .tif files of the images taken and .spm files that can be opened in any compatible software. The naming convention is film_sample_resoloution.

Scanning electron microscopy was performed on the samples using a Hitachi SU8200. The operating voltage was 20\,kV and the working distance was between 10 and 11mm. The folder "SEM" contains .tif files of the imaes taken. The naming convention is film_sample.
