Abstract AR

تم دراسة خواص تأثير هول عند درجات تلدين مختلفة لأغشية كبريتيد الرصاص المحضرة بدرجة حرارة الغرفة طريقة التبخير الحراري في الفراغ تحت ضغط 4 * 10-5 تور سمك الغشاء كان 2 مايكرو متر و لوحظ أن تركيز الحاملات n يتناقص مع تزايد درجة حرارة التلدين.

أظهرت قياسات هول أن حاملات الشحنة هي الالكترونات (أي أن التوصيلية نوع n-).

من ملاحظة الاعتمادية على درجة الحرارة، وجد أن تحركية هول، و سرعة الانجراف، و زمن عمر الحاملات، و متوسط المسار الحر تزداد مع زيادة درجة حرارة التلدين.

Abstract EN

Measurements of Hall effect properties at different of annealing temperature have been made on polycrystalline Pb0.55S0.45 films were prepared at room temperature by thermal evaporation technique under high vacuum 4*10-5 torr .

The thickness of the film was 2μm .The carrier concentration (n) was observed to decrease with increasing the annealing temperature.

The Hall measurements showed that the charge carriers are electrons (i.e n-type conduction).

From the observed dependence on the temperature, it is found that the Hall mobility (μH), drift velocity ( d) carrier life time (T ), mean free path (λ) were increased with increasing annealing temperature
