摘要：

Hybrid materials built from conjoined structures of graphene nanoribbons (GNRs) and carbon nanotubes (CNTs) have important properties for novel applications. In this communication we have performed a numerical study of these structures and have found two types: (i) CNT and GNR structures formed by van der Waals forces with a distance close to 0.35 nm and (ii) CNT and GNR structures interconnected by short (0.17 nm) and strong chemical bonds. It appears that the latter bonds essentially perturb conjoined carbon C-6 rings. The reason for the perturbation is the pseudo-Jahn-Teller effect.
