Complex elastic properties and piezoelectric activity in stoichiometric and congruent LiNbO3 single crystals
Résumé
Piezoelectric effect has been measured for stoichiometric (Li/Li + Nb = 50 mole%) and congruent (Li/Li + Nb = 48.6 mole%) lithium niobate crystals. Observations of the piezoelectric resonance allowed to investigate the temperature dependence of the complex elastic coefficient s*11. Distinct local maxima on the s″11(T) dependencies have been found.
