2. Experimental details
ZrOX thin films were deposited onto high-speed steel (AISI M2), glass and single crystal silicon substrates, by reactive dc magnetron sputtering. Details on film preparation conditions can be found elsewhere [6].
The atomic composition of the as-deposition samples was measured by Rutherford Backscattering Spectroscopy (RBS) using a 1.4 MeV He+ beam and a 2 MeV proton beam to increase the accuracy in the oxygen singnals. The analyzed area was about 0.5 * 0.5 mm2 . Ball crater tests were used to measure the thick-ness of the samples. In order to examine the film structure, X-ray diffraction experiments (XRD) were undertaken in a Philips PW 1710 apparatus, using Cu K ∝ radiation, with a step size of 0.02, a counting time of 1.25/s and a gas detector. Raman measure-ments were perfomed at room temperature with a Dilortriple monochromator, equipped with a liquid nitrogen cooled charge couple device (CCD) detector, with a resolution better than 1 cm¯¹. The excitation line, 514.5 nm, of an argon ion laser was focused onto the sample using a ×100 MS plan objective of an Olympus Microscope BHSM, in a backscattering geometry. The spectra were obtained with a measured power of about 10mWonthe sample, during an integration time of 120 s, over the range 80–1200 cm¯¹.
