摘要:

通过密度函数理论计算发现,锯齿形边缘石墨烯纳米颗粒是一种反铁磁绝缘体,在锯齿形边缘掺杂N和B后,其显示出一个强的狄拉克点.更有趣的是,我们发现,强大的狄拉克点是一个共同的特点,蜂窝结构的纳米粒子与适当的边缘网站。因此,锯齿形边缘的蜂窝状纳米结构有望为材料的设计和开发提供一个非常有用的平台。

英文摘要:

The zigzag edge graphene nanoribbon, which is an antiferromagnetic insulator, is found from the density-function theory calculation to display a robust Dirac point after N and B doping at the zigzag edge. More interestingly, we found that the robust Dirac point is a common feature of the honeycomb structure nanoribbon with appropriate edge sites. The zigzag edge honeycomb nanoribbon is therefore expected to provide a very useful platform for material design and development.
