Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

Sorry for starting a new thread that is similar to another previous one but the question I'll ask is different in fact.

Please consider the DOS of a metallic CNT given in this thread: https://www.physicsforums.com/showthread.php?t=351722

On the other hand, the DOS of 1-D structures are given as

However, it seems not possible to achieve a nonzero DOS at E=0 with this equation (the DOS of metallic CNTs are nonzero at E=0). So, I conclude that the DOS of metallic CNTs are different than this equation. Could you please give an equation for the DOS of metallic CNTs or a reference showing it?

Thank you in advance,
