N2  - Döndürerekkaplama yöntemiyle hazırlanan top tipi çinko (II) ftalosiyanin ince filmlerindielektrik durulma davranışları 5 Hz. ile 13x106Hz frekans aralığında sıcaklığa bağlı olarak (298 K – 468 K sıcaklıkaralığında) empedans spektroskopi yöntemiyle incelenmiştir. Elde edilenverilerin modellenmesinde sistemin dielektrik davranışının paralel RC eşdeğerdevre ile temsil edilebileceği görülmüştür. Filmlerde ac iletkenliğin frekansabağlılığının ωmşeklinde olduğu ve frekansın üssü olan m parametresinin kuvvetle sıcaklığabağlı olduğu gözlemlenmiştir. Deneysel olarak elde edilen ac iletkenlikverileri iki farklı model kullanılarak analiz edilmiştir. Frekansın üssü olan mparametresinin sıcaklığa bağlılığının incelenmesinde çinko (II) ftalosiyaninince filmlerde ac yük iletiminin hoplama mekanizması sayesinde gerçekleştiğisonucuna varılmıştır.
