THz Time-Domain Spectroscopy (THz TDS) is an advanced spectroscopic technique that utilizes terahertz (THz) radiation to probe the properties of materials. THz radiation falls in the electromagnetic spectrum between microwave and infrared frequencies, typically in the range of 0.1 to 10 THz. This technique is especially useful in nanotechnology for characterizing the dynamical processes and interactions at the nanoscale.
