In this study, the thermally stimulated depolarization measurements of polycrystal pellets of NaCl and KCl alkali halogen salts prepared by applying pressures to the powder of these materials have been performed. Firstly, the activation energies have been calculated from the curves of depolarization currents produced across the sample by thermal excitation, by means of the relations given by various authors for the peak shape method. Next, from these E energy values, s frequency factors have been determined. Finally, these obtained E and s values are compared with the literature, and the difference from the literature is interpreted as due to the crystal structure differences between the samples used in this study and those found in the literature.
Bu çalışmada, NaCl ve KCl Alkali halojenür tuzlarının basınç altında oluşturulan polikristal pelet numunelerin Isısal Uyarımlı Depolarizasyon ölçümleri gerçekleştirilmiştir. Isısal uyarılma ile numune uçlarında oluşan depolarizasyon akım eğrilerinden E aktivasyon enerjileri değişik araştırmacılar tarafından pik şekli yöntemi için verilen bağıntılar yardımıyla hesaplanmıştır. Bu E değerlerine bağlı olarak da frekans faktörü s belirlenmiştir. Bulunan bu E ve s değerleri, literatürde verilen değerleri ile karşılaştırıldığında görülen farkın, deneyde kullanılan numunelerin kristal yapılarının karşılaştırma yapılan numunelerin kristal yapılarından farklı olmasından kaynaklandığı sonucuna varılmıştır.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.
It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
