Abstract

Nowadays, most of the frequency intervals of electromagnetic spectrum have been intensively studied. However, there still is a gap between microwave and infrared light in the electromagnetic spectrum, named terahertz (THz) gap because of the lack of reliable radiation sources. The frequency of this gap covers the range from 0.1 to 10 THz, and the wavelength spans from 30 μm to 3 mm. The terahertz region of the electromagnetic spectrum is of critical importance in the spectroscopy of condensed matter systems. The electronic properties of semiconductors are greatly influenced by bound states whose energies are resonant with terahertz photons. In this chapter, we have reviewed terahertz spectroscopy study of III–V nitrides.
