Surface Morphology, Optical and Electrophysical Properties of Erbium-Doped Lanthanum Oxide Films Obtained by Laser Deposition

Abstract

   Thin films of lanthanum oxide doped with erbium, LaMnO3+0.5%Er2O3, deposited in a vacuum of p = 3 Pa on quartz and silicon substrates were studied under multi-pulse high-frequency f ∼ 12—15 kHz laser action on a ceramic target at a laser radiation power density of q = 81 MW/cm2. The morphology of the obtained films, transmission and reflection spectra were studied using atomic force microscopy. An analysis of the electrophysical properties of the LaMnO3+0.5%Er2O3 structure was carried out.
