Аннотация

В работе методом диэлектрической спектроскопии изучены особенности поляризационных процессов в нанокристаллических пленках йодида серебра в области термического суперионного фазового перехода и рассчитаны релаксационные и энергетические параметры данной системы. Скачкообразное изменение обнаружено для энергии активации, показателя степени частотной зависимости, функции тангенса угла диэлектрических потерь. Предложена модель микромеханизма термического фазового перехода «полупроводник — суперионник». Показано, что наряду с суперионным фазовым переходом в пленках имеет место перколяционный фазовый переход с образованием двумерного перколяционного кластера.
