Structural, Optical and Electrophysical Properties of La0.13Bi0.87FeO3 Films Obtained by High-Frequency Laser Evaporation in Vacuum
Abstract
By the method of high-frequency repetitively pulsed f ~ 10–13 kHz laser radiation with a wavelength λ = 1.064 μm and a power density q = 57 MW/cm2 on La0.13Bi0.87FeO3 target at a pressure in the vacuum chamber p = 4.6 Pa nanostructured thin films on a silicon substrate have been obtained. The morphology of thin La0.13Bi0.87FeO3 films was studied using atomic force microscopy. Transmission spectra of La0.13Bi0.87FeO3 films were obtained in the visible, near and mid-IR regions. The electrophysical characteristics of La0.13Bi0.87FeO3/Si structures were analyzed.
