A Study of the LiNbO3 and LiTaO3 Absorption Edge
Süleyman Çabuk, A. A. Mamedov · DergiPark (Istanbul University) · 1998
Optical spectroscopy methods are used to study the spectra of some oxygen-octahedral ferroelectrics - LiNbO3 and LiTaO3. Study of the role of BO6 octahedron by using spectroscopic methods can cast light on the many physical phenomena that place in LiNbO3 and LiTaO3. For these crystals, absorption edge, band gap, Urbach constants and phonon energy were found.
