Growth of Single-Crystalline Boron Nanotubes in Cu alloy


In this work we report the successful synthesis of single-crystalline boron nanotubes in Cu alloy through a novel and simple direct melt reaction process. The boron nanotubes are perfect single crystals with β-rhombohedral structure whose size can be controlled and changed. The combined results of the experimental campaign and of dynamic simulations allowed to determine that a boron nanotube in Cu alloy can be considered as a crystal skeleton, closely related to the liquid structure and solidification characteristics of the Cu-B alloy, which is significantly affected by the cooling rate and boron concentration. In addition, the stable morphology of boron nanotubes, which minimizes the energy content, is not a round tube but a parallelogram. Boron tubes with large range scale can be prepared in Cu alloys.
