Collective movement and thermal stability of fullerene clusters on the graphene layer

Abstract

Understanding the motion characteristics of fullerene clusters on the graphene surface is critical for designing the surface manipulation systems. Toward this purpose, using molecular dynamics method, we evaluated six clusters...

Nanocar swarm movement on graphene surfaces

“…The Tersoff potential has shown accurate predictions in the simulation of graphene at high temperatures, such as the amplitude of surface ripples 34 and desorption temperature of the C60 molecule from graphene. 34,35 The nanocars were modeled by the Molecular Mechanics (MM) force field [36][37][38] as previously employed in other studies. [18][19][20][22][23][24] For this purpose, we considered two atom types for carbon atoms in the nanomachines.…”

Unidirectional motion of C60-based nanovehicles using hybrid substrates with temperature gradient

“…Understanding the motion of molecules on surfaces is of great importance in developing nano-transportation systems on the surface 1 . Using experimental and computational studies, many researchers have tried to understand the surface motion of various molecules in the past decade [2][3][4][5][6][7][8][9] . The experimental tools such as scanning tunneling microscopy (STM) require highly specialized equipment for investigating the surface phenomena at nanometer scale 10,11 .…”

Fullerenes containing water molecules: a study of reactive molecular dynamics simulations

“…For designing surface manipulation systems, thermal stability and collective movement of six clusters of fullerenes were investigated by means of the MD method. 25 This study showed that as the number of fullerenes increases, they separate into large clusters at higher temperatures. In addition to the abovementioned studies, a number of reports have also reflected the properties of C 60 through MD methods.…”
