Effect of Temperature on Structure and Electrical Properties of Semiconducting Zinc Oxide (ZnO)

Abstract

Abstract This study aims to investigate the importance of ZnO as a semiconductor material, and its usages in various applications also the effect of temperature on electrical properties (Resistance-Conductivity), and the structure by X-Ray diffraction. To find the Resistance and conductivity of ZnO, three sample of commercial ZnO, Zn oxided at 950 ºC and ZnS oxided at 550 ºC have been investigated, and it founded that all samples have a similar properties of semiconductors, and also founded that the Resistance decrese by the temperature while the conductivity increases. The three samples of ZnO have been annealed at different temperatures and characterized using X-Ray. The most important and the best finding achieved through the study is commercial ZnO powder has the best structure and electrical properties that the other and this maybe for the high purity of the powder and oxygen vacancy in the oxidized powders.
