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.

本研究采用Quantum Design物理性质测量系统（Physical Property Measurement System，PPMS）对所有样品的超导特性开展电输运测试。该PPMS生成的数据可通过任意支持".dat"格式文件的软件打开。文件"230929_A_B_D_1uA"对应12 k薄膜样品A、B、D的测试数据；文件"230929_C_230929B_A"对应12 k薄膜样品C与6 k薄膜样品A的测试数据；文件"230929B_B_C_D_1uA"对应6 k薄膜样品B、C、D的测试数据。所有数据文件均将电阻、温度与磁场数据分列于带标签的不同列中。在"230929_A_B_D_1uA"文件中，12 k薄膜样品A、B、D的电阻数据分别位于标题为"Bridge 1 Resistivity (Ohm)"、"Bridge 2 Resistivity (Ohm)"以及"Bridge 3 Resistivity (Ohm)"的列中。在"230929_C_230929B_A_1uA"文件中，12 k薄膜样品C与6 k薄膜样品A的电阻数据分别位于标题为"Bridge 3 Resistivity (Ohm)"与"Bridge 1 Resistivity (Ohm)"的列中。在"230929B_B_C_D_1uA"文件中，6 k薄膜样品B、C、D的电阻数据分别位于标题为"Bridge 1 Resistivity (Ohm)"、"Bridge 2 Resistivity (Ohm)"以及"Bridge 3 Resistivity (Ohm)"的列中。由于所有文件均将磁场与温度数据整合存储，需手动拆分两类数据。所有文件中，磁场数据位于标题为"Magnetic Field (Oe)"的列中，温度数据则位于标题为"Temperature (K)"的列中。

本研究采用搭载SynapsePlus背照式深耗尽（Back-Illuminated Deep Depletion，BIDD）电荷耦合器件（Charge-Coupled Device，CCD）的Horiba LabRAM HR Evolution拉曼光谱仪，搭配532 nm激光器开展拉曼光谱测试。测试数据存储为".txt"格式文件，所有文件遵循统一命名规则：film_sample_532。例如，"230929_A_532"对应批次230929的样品A，其中"230929"对应12 k薄膜，"230929B"对应6 k薄膜。每个文件包含两列数据，第一列为拉曼位移，第二列为拉曼强度。
