Кинетика деформации ВАХ оксидных варисторных структур, обусловленная перезарядкой локализованных состояний
Анотація
Проведено моделирование деформации импульсных вольт-амперных характеристик (ВАХ) отдельного межкристаллитного потенциального барьера при переходных процессах поляризации/деполяризации, связанной с перезарядкой поверхностных электронных состояний, которые обусловливают этот барьер. Установлено, что в зависимости от концентрации и степени заполнения этих поверхностных состояний электронами воздействие постоянного напряжения может привести к смещению импульсных ВАХ в область больших или же малых токов. Показана возможность применения найденных закономерностей для керамических варисторных структур. Предложенная модель позволяет интерпретировать наблюдаемые при испытаниях варисторов на ускоренное старение «аномальные» эффекты, такие как возрастание классификационного напряжения и уменьшение мощности активных потерь.
