Study of thin films of LiNbO3 using FTIR and Raman spectroscopy
Original language description
Lithium niobate (LiNbO3) is a material which can be used in many applications. LiNbO3 thin films were studied for the development of doped planar waveguides using Pulsed Laser Deposition (PLD) method from two targets. The films were deposited by PLD on SiO2/Si and (0001) sapphire substrates at temperatures 650°C, 700°C, 750°C, from one crystalline and two sintered LiNbO3 targets using KrF excimer laser. The film thickness was 680 nanometers. Two techniques - Fourier Transform Infrared Spectroscopy (FTIR) and Raman Spectroscopy - are used to characterize the dependence of the deposited thin films on the deposition conditions. These methods characterize the materials by monitoring their phonons whose spectra are sensitive to film deposition parameters. Bulk LiNbO3 has rhombohedral crystal structure with two chemical units per primitive cell, it means, that 30 degrees of freedom are distributed between A1 and E irreducible representations.
