摘要: Electrical complex ac conductivity of the compound Li0.9[Ni1/3Mn1/3Co1/3]O1.95 has been studied in frequency range 10 Hz–2 MHz and temperature 93–373 K. It observed that dependence obeys a power law is quite weak. The experimental data have analyzed framework several theoretical models based on quantum mechanical tunneling classical hopping over barriers. electron dominant from 93 K to 193 A crossover relaxation mechanism polaron at Out discussed, are consistent with for conductivity. various parameters obtained fits results real imaginary parts predictions these reasonable.
