Abstract This study deals with the effect of Cu on hydroxyapatite (HAp) thin films silicon substrates prepared by pulsed laser deposition (PLD) technique for concentrations ranging from 0 to 0.8 wt.%. Fourier transform infrared spectroscopy and Raman provide additional evidence HAp in films, which exhibit characteristic bands such as 960 cm −1 phosphate ion band. The X‐ray diffraction patterns confirm presence HAp, without copper‐related peaks, suggesting that it is not incorporated into lattice, present an amorphous phase. photoelectron confirms possibly related adsorption 2+ surfaces through electrostatic or interactions (PO 4 ) 3− groups. Atomic force microscopy shows roughness varies depending absence copper ions. Finally, density functional theory kinetic Monte Carlo simulations explain effects atomic diffusion clustering. These changes correlate contact angle values, indicating formation hydrophobic due inclusions.
