UNIVERSAL RELAXATION BEHAVIOR OF AMORPHOUS LINBO3

Amorphous LiNbO3 was produced by the twin-roller quenching method, and the frequency-dependent dielectric constant and conductivity were mea sured between 100 Hz and 15 MHz. The temperature was varied from -53 d egrees C to 219 degrees C. Relaxation and conduction mechanisms were o bserved and fitted by using the equations of ion-hopping conduction an d Davidson-Cole relaxation. The universal behavior, given by Dixon et al., of the Li+ ion in an amorphous LiNbO3 sample is discussed. Conduc ting behaviors are also considered.
