| In this paper the results of investigations of pure and Ca-doped CoO thin films deposited by PLD technique are presented. The studies carried out for variable Ca content allowed to establish optimal conditions for good quality oxide films preparation. The microstructure, chemical/phase composition and morphology of obtained thin films were examined by means of diverse techniques (SEM, EDS, XPS and XRD). For estimation of deposited Ca-doped CoO films quality the nanohardness and scratch tests (adhesion) were performed. Obtained results confirm that using PLD technique it is possible to carry stoichiometric composition of (Co,Ca)O from target to single crystal substrate and allow to conclude that the calcium dopant concentration (chemical composition) influence on the morphology and measured properties of deposited (Co,Ca)O films. |
