摘要：

We review the stability and electronic properties of composite BxCyNz nanotubes, including BN-, BC2N- and B-doped carbon nanotubes. We show in particular that BC2N systems are driven towards the segregation of pure C and BN sections. The same process of segregation into BC3 islands is evidenced in the case of B-doped carbon nanotubes. These spontaneous segregation processes lead to the formation of quantum dots or nanotube heterojunctions with potential important technological applications. (C) 2000 Elsevier Science B.V.
