題名: | Nanocables made of a transition metal wire and boron nitride sheath: Density functional calculations | 作者: | 楊志開 Yang,Chih-Kai; Zhao,Jijun; Lu,Jian Ping |

Our calculations indicate that transition metal wires can be inserted inside a variety of zigzag BN nanotubes exothermically. In particular a cobalt wire and the BN tube interact just like two giant molecules. The weak interaction between the BN tube and the wire ensures a low binding energy and a high magnetic moment that comes solely from the transition metals. High spin polarization at the Fermi level also indicates that the hybrid structure can be used as a nanocable for spintronic applications | 關聯: | Physical Review B,74,235445-1-235445-6 | 資料類型: | article |
