النتائج المعتمدة على نموذج لوح الكرافين مستخلصة كدالة القطر و chirality لأنبوب الكاربون النانوي.
هذه الخاصتين الأخيرتين بدورهما يقرران أما أنبوب الكاربون النانوي معدني أو شبه موصل.
تم حساب الأقطار للأنابيب الثانوية نوع المتعرج و الكرسي بالاعتماد على فجوات الطاقة Ev (0.922، 0.773) ما يعادل nm (1300، 1550) طول موجي.
تم محاكات كثافة الحالة الالكترونية لفجوات الطاقة مع مستوى الطاقة الأول 11E باستخدام MATLAB.
Abstract EN
In this paper, the electronic density of state (DOS) of a carbon nanotube has been calculated using Tight Binding (TB) method.
The result based on the graphene sheet model, is deduced as a function of the nanotube chirality and diameter.
These two latter properties in turn decide wither the CNT is metallic or semiconducting.
The diameters for zigzag and armchair type of CNT were calculated according to energy gaps of (0.773), (0.922) eV the equivalent of 1550nm and 1300nm wavelength.
The DOS of these energy gaps was simulated with the first energy level (E11) using MATLAB.
