Abstract
Lithium niobite (LiNbO2) single crystals fabricated via liquid phase electro-epitaxy are studied by Raman spectroscopy. We present the Raman spectra of the pristine and chemically delithiated LiNbO2 crystals under ambient conditions. Two characteristic experimental Raman peaks located at 456 cm−1 and 640 cm−1 are assigned to the O E2g and O A1g phonon modes respectively, as determined from first principles-based calculations. Furthermore, by chemically delithiating the crystals it is shown that the spectral changes of the O E2g can be used to capture lithium content variation within the structure.
