SURFACE MORPHOLOGY AND OPTICAL AND ELECTROPHYSICAL PROPERTIES OF La0.4Ba0.6CaO3 FILMS OBTAINED BY LASER DEPOSITION

Nanostructured thin films on a silicon substrate were obtained by high-frequency repetitively pulsed (f similar to 10-15 kHz) laser action with a wavelength of 1.064 mu m and a power density q = 54 MW/cm(2) on La0.4Ba0.6CoO3 ceramics at a vacuum chamber pressure p = 2.2 Pa. The morphology of the obtained films was studied using atomic-force microscopy. Features of transmission spectra in the visible, near-, and mid-IR regions were revealed. The electrophysical properties of the La0.4Ba0.6CoO3 structure were analyzed.
