Abstract

Terahertz (THz) electromagnetic signals will certainly push the border in nanotechnology due to higher optoelectronic performance. The main purpose of this work is to analyze and study the coherent terahertz time-domain spectroscopy (THz-TDS) signals which provide a precise approach to achieve the electromagnetic absorption and dispersion responses of uniform and flat parallel face carbon nanostructures thin-films deposited on the transparent quartz substrate in the THz regime. We employ the THz differential analysis without concerning the complex iteration algorithm to extract the optical properties parameters of multi-walled carbon nanotubes (MWNTs) thin-films.
