Hydroxyapatite Ca10(PO4)6(OH)2 (HAP) is a natural calcium phosphate and a major constituent of human bone and teeth. As such artificial HAP is bioactive and has been used in a variety of biomedical applications such as orthopedic devices, dental replacements, tissue engineering, antimicrobial coating applications, and drug delivery systems (DDS). It can be engineered to be bioinert or bioabsorbable through control of crystallinity, porosity, and material polarization. Here we report on the synthesis of hydroxyapatite-titanium composite thin films using pulsed laser deposition (PLD) technique. Films were deposited on Si (100) and Sapphire (0001) single crystal substrates and were annealed in air or nitrogen/water vapor at various temperatures to study crystallization properties. Fourier transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), energy dispersive x-ray spectroscopy (EDS), and atomic force microscopy (AFM) characterization techniques were employed in the study of the films after deposition and after annealing. All as-deposited thin films were amorphous as seen by XRD and FTIR. AFM analysis showed all films contained micron sized particles embedded into them. Root mean squared (RMS) roughness of pure HAP films was ~ 100 nm and decreased to ~50 nm as composite content increased. Film roughness in between particles remained smooth to within 1 nm. Annealing of thin films on Si (100) in air resulted in very limited crystallization. However, annealing of thin films on sapphire in nitrogen/water vapor resulted in significant crystallization as seen in both XRD and FTIR with the added features of probable texturing resulting in the prominent presence of (002), and (112) diffraction peaks.
