【摘要】 采用分子动力学方法模拟铜铝纳米薄膜相对侧向移动的相互作用能.研究了铜薄膜的侧向位移从0到50时温度、相互作用间距、表面形貌和表面粗糙度对作用能的影响.结果表明,相互作用强度随温度的增加而增大,随相互作用间距的减小而增大,随表面粗糙度的增大而减小.为研究薄膜在纳米尺度的相互作用提供了一个新的方法.更多还原

【Abstract】 Molecular dynamics simulations have been carried out to investigate the interactions between noncontact copper and aluminum nano-films with lateral movement.Effects of temperature,distance,surface morphology and surface roughness on the interaction strength are studied when the lateral displacement increases from 0to 50.Results show that the interaction strength increases with increasing temperature,increases with decreasing distance and decreases with increasing surface roughness.It provides a new method to study the interactions between films at nanoscale.更多还原
