The Features.of the Temperature Dependence of Photoconductivity in Ferroelectrics-Semiconductors of the System Sb2S3-Sb2Se3
Abstract
In this paper the temperature dependence of photoconductivity in ferroelectric-semiconductor crystals of Sb2S3-Sb2Se3 systems has been investigated. In crystals close to Sb2S3 composition except for the intrinsic maximum of photoconductivity appropriate to fundamental absorption. the additional maximum has been observed at low temperatures related to ferroelectric activity of crystals, which disappear at more high temperatures (T>300K). It is established that the forbidden zone width shows anomalous behavior in the temperature range of phase transitions. The ranging of coefficient of temperature dependence of the forbidden zone width has been determined.

Abstract
Bu makalede ferro-elektrik yarl iletken kristalle sistemler Sb2S3-Sb2Se3'de sicakll§a ba§ll foto iletkenlik incelendi. Kristallerde yaklaşık temel sogurma foto iletkenliğinin maksimumu hariç, Sb2S3 yakin bile;iklere sahiptirler. Kristalin ferro-elektrik aktivitesine bagli olarak, düsük stcaktlklarda ortaya çlkan, yüksek sicakllklarda (T > 300 K) ise kaybolan itave maksimum gözlenmi§tir. Oluşturulan yasak bant gösteriyor ki, faz geçişi sıcaklığı aralığında anormal davranış görülmektedir. Yasak bant genişliğinin sıcaklığa bağımlılık sabitinin değişim aralığı belirlenmiştir.
