Self-assembly of a parallelogram black phosphorus ribbon into a nanotube

Abstract

A nanotube from single-layer black phosphorus (BP) has never been discovered in experiments. The present study proposed a method for the fabrication of a BP nanotube (BPNT) from a parallelogram nanoribbon self-assembled on a carbon nanotube (CNT). The nanoribbon has a pair of opposite sides along the third principal direction. According to the numerical simulation via molecular dynamics approach, we discover that a wider BP nanoribbon can form into a series of chiral nanotube by self-assembly upon CNTs with different radii. The radius of a BPNT from the same ribbon has a wide range, and depends on both geometry of the ribbon and the CNT. One can obtain a BPNT with the specified radius by placing the ribbon nearby a given CNT. The method provides a clue for potential fabrication of BPNTs.

Locomotion of the C60-based nanomachines on graphene surfaces

“…Here, σ and ε are the van-der-Waals (vdW) radius and depth of atomic interaction potential for each pair of species, respectively. The parameters related to each atom pairs are listed in Table 1 based on previous studies on non-bonding interactions [46][47][48][49] . The cut-off radius, r cut of 12 Å is utilized in this work to reduce computational expenses.…”

The electronic and optical properties of silicon doped on arsenic and antimony nanotubes: a first-principles study

“…Graphene nanotubes, [1][2][3][4] silicon nanotubes, [5][6][7][8][9][10][11][12][13] and phosphorus nanotubes [14][15][16][17] have attracted a lot of attention due to their superior performance, such as ordered tubular structures and controllable electronic and optical properties. Arsenene and antimonene are mechanically stable and have high carrier mobility, [18][19][20] which introduces new possibilities to the fabrication of optoelectronic devices.…”
