Abstract
Ferroelectric Bi4Ti3O12ceramics are fabricated by conventional solid-state reaction process. The current-voltage characteristic of Bi4Ti3O12sample exhibits a voltage-controlled negative differential resistance behavior at low field (E≤100V/mm), and an obvious PTC effect appears at around 100°C on the resistance-temperature curve. Based on conducting filament model about electrical transport, instead of Heywang-Jonker model, the experimental results of Bi4Ti3O12ceramics are suitably explained.
