Abstract AR
في هذا العمل, حضر سليكون مسامي بطريقة كيميائية و بمساعدة الليزر.
تم دراسة الخصائص البصرية و التركيبة للسيلكون المسامي باستخدام مجهر القوى الذرية و مطياف FTIR.
بين طيف FTIR تشكيل (1, 2 = x) SiHx و الأصره O – S.
يظهر مجهر القوة الذرية AFM خشونة السطح (لوحظ أن nm 1.52 RMS مع ليزر و nm 86.1 بدون الليزر).
و هرم مثل سطح التلال على كامل السطح و التي يمكن اعتبارها نقطة تكاثف لتشكيل مجموعات الصغيرة و التي تلعب دورا قويا في الإضاءة المرئية.
Abstract EN
In this work porous silicon where prepared by chemical etching assisted with laser.
The structural and optical properties of porous silicon are investigated using atomic force microscopy (AFM) and FTIR spectroscope.
FTIR spectrum exhibit the formation of SiHx (x=1,2) and Si-O bonds.
The atomic force microscopy AFM investigation shows the surface roughness (RMS observed was 1.52nm with laser and 1.
86 nm without laser ) and pyramid like hillocks surface on entire surface which can be regarded as a condensation point to form small skeleton clusters which plays an important role for the strong visible luminescence.
