Abstract

In chiral gold nanotubes, alternating electric current generates an electromagnetic field; under these conditions, the nanotubes become emitting solenoid nanoantennas. With the use of the Maxwell equations and taking into account the geometry of nanotubes, their band structure, and the ballistic model of electron transfer, we have calculated the alternating axial magnetic and azimuthal electric fields generated by helical currents in chiral gold nanotubes. The calculations demonstrate that large alternating magnetic and electric fields can be generated in nanoscale volumes of gold nanotubes and that the eigenfrequencies of the field components are in the X-ray range.

交流电影响下手性金纳米管的辐射

摘要

在手性金纳米管中，交流电会产生电磁场。在这些条件下，纳米管成为发射螺线管纳米天线。通过使用麦克斯韦方程组，并考虑到纳米管的几何形状，其能带结构以及电子转移的弹道模型，我们计算了手性金纳米管中螺旋电流产生的交变轴向磁场和方位电场。计算表明，在纳米级体积的金纳米管中可以产生较大的交变磁场和电场，并且场分量的本征频率在X射线范围内。
