Abstract AR
تم في هذا البحث تحضير أغشية رقمية ل CuAl1-XFexS2 بطريقة الرش الكيميائي الحراري و بدرجة (593) كلفن و لقيم x من 0 إلى 1. تم دراسة خواص الامتصاصية الضوئية و بدرجة الغرفة و لمختلف قيم x كما تم حساب المقاومة الكهربائية ضمن درجة الحرارة (400 - 300) كلفن و لمختلف قيم x. من دراسة طيف الامتصاصية اتضح وجود انتقالات إلكترونية اثنين, الأول يعود لوجود الحديد و يكون بحدود 2.55 ev و لا يعتمد على تركيز الحديد.
أما الانتقال الثاني فيكون معتمد على تركيز الحديد و يتغير ضمن المدى 3.35 ev عند x=0 إلى 3.65 عند x=1.
Abstract EN
CuAl1-xFexS2 thin films have been prepared using the chemical spray pyrolysis technique with substrate temperature (Ts) at 593°K for which x varies from 0 to1.
The optical absorption at room temperature is studied for the different Fe concentrations.
The electrical resistance is measured in the temperature range (300-400)°K for different x values.
The absorption optical spectra show two electronic transitions.
The first is due mainly to the iron presence, which is around 2.55 eV, and is concentration independent.
The second is concentration dependent changing from 3.35 eV for x=0 to 3.65 eV for x=1.
The introduction of iron atoms into the ternary compound CuAlS2 has a drastic effect on the electrical properties: The amorphous samples go through a transition from semiconductor behavior to a semi-metallic one for x as low as 0.1.
