中文摘要	Random Sb-SiN films consisting of random small Sb particles embedded in a SiN thin film were deposited by radio-frequency magnetron sputtering. Specimens comprising in order a random Sb-SiN film and an optical-phase-change recording layer were exposed to a focused laser beam. It was shown that, with a random Sb-SiN layer deposited above the recording layer, the ablation of the recording layer occurred much faster and under much lower power than that of a single recording layer. Scanning Near-field Optical Microscope (SNOM) images of the transmitted light after passing through the random Sb-SiN film were produced as well as a Finite Difference Time Domain (FDTD) calculation of the field distribution. They both showed a local optical near-field enhancement due to multiple scattering effects of the Sb nanoparticles. This is promising for application in super-resolution optical storage to got a higher Carrier to Noise Ratio (CNR).
