Self-assembly of a nanotube from a black phosphorus nanoribbon on a string of fullerenes at low temperature

Abstract

A string of fullerenes is used for generating a nanotube by self-assembling of a black phosphorus (BP) nanoribbon at the temperature of 8K. Among the fullerenes in the string, there are at least two fixed fullerenes being placed along the edge of the BP ribbon for keeping its configuration stability during winding. By way of molecular dynamics simulations, it is found that a successful generation of a BP nanotube depends on the bending stiffness of ribbon and the attraction between the fullerenes and the ribbon. When the attraction is strong enough, the two edges (along zigzag direction) of the BP ribbon will be able to bond covalently to form a nanotube. By molecular dynamics approach, the maximum width of the BP ribbon capable of forming a nanotube with a perfect length is investigated in three typical models. The maximum width of the BP ribbon becomes larger as the string contains more fullerenes. This finding reveals a way to control the width of the BP ribbon which forms a nanotube. It provides guidance for fabricating a BP nanotube with a specified length, being the same to the width of ribbon.
