【摘要】 结构缺陷、掺杂等可以导致纳米管的自旋极化,而自旋极化的纳米管可以利用载流子的自旋状态作为信息载体,实现一维的自旋电子传输.具有不同自旋极化结构的纳米管,根据其电子结构、自旋极化性质和输运性质的不同,可以用于实现不同用途的自旋电子器件.很多有关自旋极化的纳米管的理论和实验工作已经展开,然而其中仍有很多物理问题有待深入研究.更多还原

【Abstract】 Structural defects and dopingcan result in spin polarization in nanotubes, which could then use electron spin as the information carrier in one-dimensional spintronic devices. Nanotubes with different spin polarization structures may possibly be applied in different spintronic devices. Considerable experimental and theoretical efforts have been devoted to this field, but there are still many unclear problems to be studied and solved.更多还原
