High-Field Terahertz Time-Domain Spectroscopy of Single-Walled Carbon Nanotubes and CuO

Section 5.1 of this chapter gives a brief overview of some techniques utilised to generate high-field THz pulses and their applications in spectroscopy. Section 5.2 then describes the setup and operation of the high-field THz-TDS system developed as a part of this doctoral work. Section 5.3 then explores the use of indium antimonide (InSb) as a test material for the high-field THz-TDS system, before Sects. 5.4 and 5.5 present some preliminary results on high-field THz spectroscopy of highly-conductive single-walled carbon nanotube (SWCNT) films and electromagnons in CuO.
