摘要：
The insulator band gap Eg of graphene nanoribbons, one side of which is completely coated with hydrogen, is calculated numerically. It is shown that Eg is ∼1.5 eV narrower than the band gap in graphane nanoribbons with the same width w and steadily increases with decreasing w. As in graphane nanoribbons, the atomic structure of nanoribbon edges has virtually no effect on the value of Eg.
