STUDY OF ELECTRICAL-CONDUCTION BEHAVIOR OF THE SR1-XLAXTI1-XNIXO3 (X-LESS-THAN-OR-EQUAL-TO-0.10) SYSTEM

Electrical conduction behaviour of the Sr1-xLaxTi1-xNxO3 (x less-than- or-equal-to 0.10) system has been studied by complex plane impedance s pectroscopy and AC conductivity measurements in the temperature range 300-575 K Both these studies show that conduction occurs by a Debye-ty pe loss process at low temperatures and by excitation of charge carrie rs at valence band edge and hopping at energies close to it at high te mperature among localized nickel sites mainly responsible for conducti on.
