Peculiar width dependence of the electronic properties of carbon nanoribbons
Peculiar width dependence of the electronic properties of carbon nanoribbons
Nanoribbons (nanographite ribbons) are carbon systems analogous to carbon nanotubes. We characterize a wide class of nanoribbons by a set of two integers $<p,q>$, and then define the width $w$ in terms of $p$ and $q$. Electronic properties are explored for this class of nanoribbons. Zigzag (armchair) nanoribbons have similar …
