دراسة تأثير درجة حرارة القاعدة في الانتقالات الالكترونية لأغشية أوكسيد الكادميوم الرقيقة

الملخص EN

This research including studying the influence of substrate temperature on electronic transition of (CdO) thin films.

These films of (400nm) thicknees, had been prepared by the method of chemical spray pyrolysis on glass substrates at three different substrates temperatures (400,450,500)0C.

The prepared films were examined by x-Ray diffraction technigue, which showed that all prepared films are polycrystallin.

The absorption cofficient, and the direct energy gap were calculated.

It has been found that the absorption cofficient decrease with increases substrates temperatures, and that optical energy gap increased with increasing substrates temperatures.
