Journal ArticleDOI
Terahertz Time-Domain Spectroscopy of Solids: A Review
TL;DR: The terahertz time domain spectroscopy (THz-TDS) as mentioned in this paper has been used extensively in the characterization of solids, such as semiconductors, superconductors, polymers, and photonic crystals.
Journal ArticleDOI
Measurement of complex optical constants of a highly doped Si wafer using terahertz ellipsometry
TL;DR: In this paper, a terahertz (THz) time-domain spectroscopy combined with ellipsometry was proposed and demonstrated with a Si wafer with low resistivity.
Journal ArticleDOI
Spectroscopy by pulsed terahertz radiation
TL;DR: In this paper, the principles of various types of terahertz time domain spectroscopies (THz TDSs) and their applications to the characterization of semiconductors are described.
Journal ArticleDOI
Terahertz radiation from coherent antiferromagnetic magnons excited by femtosecond laser pulses
TL;DR: In this article, the terahertz (THz) radiation emitted from antiferromagnetic (AFM) single-crystal nickel oxide irradiated with femtosecond laser pulses was observed.
Journal ArticleDOI
Measurement of the dielectric constant of thin films by terahertz time-domain spectroscopic ellipsometry.
TL;DR: The measured dielectric constants of doped GaAs thin films show good agreement with predictions of the Drude model, even though the film thickness is of the order of a tenth of the penetration depth of the THz waves.
