We employed X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy (UPS), and argon cluster ion beam (ArCIB) to analyze the surface properties of various nanocrystalline diamond (NCD) materials. These included boron-doped NCD, nanodiamond particles (NPs) and monocrystalline diamond samples. Our objective was to determine the surface composition, sp2/sp3 chemical bonding types, surface terminations after plasma functionalization, and electronic properties of the diamond samples, including surface band bending and electron affinity. The analysis involved sample preparation using chemical vapor deposition (CVD), photoemission measurements, and data analysis. This work serves as a foundation for further research exploring the applications of diamond materials in electronics, such as (quantum) sensors, and in biomedicine, for drug delivery and imaging.
