The impact of isotopes on thermal transport in boron nitride nanotubes (BNNTs) and boron nitride white graphene is systematically studied via molecular dynamic simulations. By varying the concentration of the B-10 isotope in these materials, we find that thermal conductivity ranges from 340 to 500W/m(-1) K-1, closely agreeing with experimental observations for isotopically pure and natural (19.9% B-10) BNNTs. Further, we investigate the interplay between dimension and isotope disorder in several C-based materials. Our results show a general trend of decreasing influence of isotope disorder with dimension of these materials.
