Ar掺杂碳纳米豆荚中C<sub>60</sub>富勒烯的碰撞与能量传递

Ar掺杂碳纳米豆荚中C₆₀富勒烯的碰撞与能量传递

摘要: 以C₆₀富勒烯之间掺杂有不同浓度Ar原子的碳纳米豆荚为研究对象,采用分子动力学方法,模拟了纳米豆荚中C₆₀富勒烯之间的碰撞与能量传递,分析了入射C₆₀富勒烯初始能量、Ar掺杂浓度对能量传递率的影响。研究表明,C₆₀富勒烯之间是通过相互压缩变形来传递能量的;入射C₆₀富勒烯的初始能量以及Ar掺杂浓度越低,C₆₀富勒烯间的能量传递率就越高。

Abstract: By using MD（molecular dynamics） method,the collision and energy-transmission of C₆₀ fullerenes in Ar doped nano-peapod was simulated,and the effect of the doped-Ar density ρ and the initial energy E₀ of the incident C₆₀ fullerene on the energy-transmission rate was analyzed.It is shown that（1） the C₆₀ fullerenes in the nano-peapod transfer energy by compressing each other,and（2） the lower the Ar density ρ and the energy E₀ of the incident C₆₀ fullerene are,the higher the energy-transmission rate of C₆₀ in the nano-peapod is.
