Abstract AR
تم تحضير نوعين من افلام كبريتيد الكاديميوم بواسطة طريقة "الطباعة على الشبكة"، مطعمة و غير مطعمة، ثم تمت دراسة الخصائص الكهربائية لهذه الأفلام بواسطة جهاز كيثلي ميتر Kiethley Picoammeter and Voltage Source و عند قياس خصائص الموصلية الضوئية وجدنا أن قيمة الحساسية الكهربائية (Iphoto / Idark) للأفلام غير المطعمة و الأفلام المطعمة حيث كانت قيمتها 2 X 103 و 6 X 103 على التوالي كما تم حساب المقاومة النوعية للأفلام غير المطعمة فوجد أنها تساوي 1011 اوم.سم و هي القيمة المسجلة لمركب كبريتيد الكاديميوم و قد أظهرت النتائج أيضا زيادة ملحوظة في قيمة الموصلية الكهربائية و بالتالي تطعيم.
أما حساب طاقة التنشيط وجد أنها تساوي (0.778eV) للعينات المطعمة و (0.449eV) للعينات الغير مطعمة.
Abstract EN
Two sets of CdS films were prepared, doped and undoped films, by screen printing technique and investigated by Kiethley Picoammeter and Voltage Source.
When we measured the photoconductivity of these films we have found that photosensitivity (Iphoto / Idark) for the undoped and doped films are( 2x103)and( 6x103) respectively.
The resistivity of the undoped CdS films also Calculated, its value was (1011ohm.cm), and that is the standard value given to resistivity of the CdS compound.
The results also showed that increase in the photoconductivity; consequently a decrease in the resistivity by increase in temperature and 0.5% doping of CuCl2.
The values of activation energies were calculated and their values were (0.778eV) for doped CdS samples and (0.449eV) for undoped.
