Effect of Nanoscale Defects on the Physical Properties of Lithium Niobate and Lithium Tantalate Crystals
The elastic, ferroelectric, and transport properties of congruent lithium niobate and lithium tantalate crystals are studied in the temperature range of 77–450 K, depending on the conditions for recovery annealing. Significant changes in the elastic moduli and electrical conductivity that correlate...
