Raman spectroscopy of lithium niobate (LiNbO3) − Sample temperature and laser spot size effects
The Raman spectrum of lithium niobate (LiNbO3) was investigated in the 83–823 K temperature range and as a function of different laser spot sizes. The measurements considered a Z-cut (congruent, undoped) LiNbO3 crystal, HeNe laser excitation (632.8 nm photons), and the zx,xyz¯ geometry. The main LiN...
