Abstract
Growing coaxial nanotubes Heterostructures of highly crystalline two-dimensional materials such as graphene, hexagonal boron nitride (hBN), and molybdenum disulfide (MoS 2 ) are now routinely assembled from films or grown as layers. Xiang et al. report the growth of one-dimensional analogs of these heterostructures on single-walled carbon nanotubes (SWCNTs) through a chemical vapor deposition (see the Perspective by Gogotsi and Yakobson). Single-crystalline monolayers or multilayers of hBN or MoS 2 were grown that maintained the electrical conductivity of the SWCNT. A monolayer of MoS 2 was grown on a trilayer of hBN that encapsulated a SWCNT. Science , this issue p. 537 ; see also p. 506
