Fano-type transmission in carbon nanotube array with Al ₂O ₃

Fano-type transmission, of which the specifics lie in continuum and resonant transmission, has been exploited in various areas since Fano published his study [1]. In this paper, we show macroscopic transmission fitted well with Fano analysis, using a sample composed of Al ₂O ₃ and multi-wall carbon nanotube. In addition to fitting, the properties of Fano-type transmission were shown to be its resonance and the interference of continuum and resonant transmission, of which the quantity was also estimated, in a similar way to Genet's result [9], and it was found that the resonance was made by carbon nanotubes (CNTs); from this, we can also conclude that CNTs have good conductivity for cavity.
