金纳米管中的手征电流

Chiral currents in gold nanotubes

D. Zs. Manrique, J. Cserti, C. J. Lambert

摘要:

结果提出的电子电流在金手性纳米管(AuNTs)。从(4,3)和(5,3)AuNTs的能带结构出发,我们发现其手性电流的大小比碳纳米管中的大。我们还计算了相关的磁通量内的管,并发现这是高于碳纳米管的情况下。虽然(4,3)和(5,3)AuNT携带的横向动量大小相似,但前者携带的低偏置磁通量远大于后者。这是因为(4,3)AuNT携带的低偏压纵向电流明显小于(5,3)AuNT。

英文摘要:

Results are presented for the electron current in gold chiral nanotubes (AuNTs). Starting from the band structure of (4,3) and (5,3) AuNTs, we find that the magnitude of the chiral currents are greater than those found in carbon nanotubes. We also calculate the associated magnetic flux inside the tubes and find this to be higher than the case of carbon nanotubes. Although (4,3) and (5,3) AuNTs carry transverse momenta of similar magnitudes, the low-bias magnetic flux carried by the former is far greater than that carried by the latter. This arises because the low-bias longitudinal current carried by a (4,3) AuNT is significantly smaller than that of a (5,3) AuNT.
