中文摘要：

考虑到迄今为止实验上尚不能制备含有上百个原子的自由单原子链,本文提出利用探针从graphene中拉伸较长单原子碳链的设想,并通过分子动力学计算发现,室温下可以利用C60探针以1m/s的速度从graphene的zigzag边缘拉出较长的一维单原子碳链,为实验提供了一种制备单原子碳链的可能方案.

英文摘要：

Considering that free monatomic chain containing hundreds of atoms has not been prepared so far,an experiment method for preparing monatomic carbon chain from graphene by nano probe is proposed based on classical molecular dynamics simulation. We show that longer monatomic carbon chain can be pulled out from the zigzag edge of graphene by C60 tip with the pulling speed of 1 m /s at room temperature.
