| 英文摘要 | We theoretically studied the ferromagnetism/antiferromagnetism (fm/afm) transition between single-wall carbon nanotubes (swcnts) induced by chemical modifications of semihydrogenation (sh-)and full-amination (nh2-). we found that armchairs with large diameters of sh-cnts (n > 3) possess fm functions with intense magnetic moments, while armchair nh2-cnts (n = 4, 6, 8) are antiferromagnetic semiconductors. the fm/afm transition is mainly dominated by different chemical modifications and sizes of swcnts whose distance between carbon atoms of unpaired electrons can regulate the intensity of p-p spin interactions. moreover, the zigzag sh-cnts and nh2-cnts are nm semiconductors. thus, the electronic and magnetic properties of the sh- or nh2-cnts can be precisely modulated by controlling the hydrogenation or amination on the different types and diameters of cnts, which provides a new and also simple process for magnetism optimization design in swcnts. |
