Анотація

На монокристалiчних зразках твердих розчинiв (Cu1−xAgx)7GeS5I були проведенi iмпеданснi вимiрювання у дiапазонi частот вiд 10 Гц до 300 кГц та в iнтервалi температур 292–383 K. Вивчено температурну i частотну залежностi електропровiдностi твердих розчинiв (Cu1−xAgx)7GeS5I. На основi аналiзу дiаграм Найквiста та з використанням електродних еквiвалентних схем були встановленi значення iонної та електронної компонент електропровiдностi. Дослiджено концентрацiйну поведiнку iонної та електронної провiдностi, а також концентрацiйну поведiнку вiдповiдних енергiй активацiй. Проаналiзовано спiввiдношення iонної та електронної компонент електропровiдностi для твердих розчинiв складу (Cu1−xAgx)7GeS5I.
