Temperature Conduction

KNN room-temperature conduction is associated with hole transport and can be suppressed by Mn-doping; a less leaky hysteresis loop is obtained. At high temperatures conduction is dominated by ionized oxygen vacancies motion. From grains and grain-boundaries resistance oxygen vacancies in KNN and Mn-doped KNN ceramics are mainly located at grain-boundaries.
