| Abstract Scope |
Raman spectroscopy is utilized to determine the characteristics of displacement damage in Lithium Niobate (LiNbO3). Due to its linear and non-linear optical characteristics, piezoelectric, pyroelectric, and ferroelectric-paraelectric phase transition properties, LiNbO3 is widely used in opto-electronics and acoustic devices. Recently, it has grabbed attention as substrate material in semiconductor technology. Y/36°-cut LiNbO3 substrates were irradiated with protons. Analysis of Raman spectra of the proton-impacted region revealed the effect of irradiation damage on vibrational properties of LiNbO3 at two different wavelengths. A Peak shift, reduction of intensity and broadening of Raman E(TO) and A1(LO) mode peaks located at 369 and 878 cm-1, respectively, were observed. These are attributed to the lattice deformation and change in Nb-O bond stretching vibration caused by point defects. For nuclear energy applications, LiNbO3 is an attractive candidate for surface acoustic wave(SAW) devices. These devices offer a compact and wireless sensing solutions for temperature, pressure, and vibration. |
