TL;DR: The 2017 roadmap of terahertz frequency electromagnetic radiation (100 GHz-30 THz) as mentioned in this paper provides a snapshot of the present state of THz science and technology in 2017, and provides an opinion on the challenges and opportunities that the future holds.
Journal ArticleDOI
Simulation of terahertz generation at semiconductor surfaces
TL;DR: In this article, a three-dimensional semiclassical Monte Carlo model is presented to describe fast carrier dynamics in semiconductors after photoexcitation, and the authors show that a magnetic field enhances THz emission by rotating the emitting dipole with respect to the sample surface, leading to an increased coupling of radiation through the surface.
Journal ArticleDOI
Terahertz quantum cascade lasers with >1 W output powers

TL;DR: In this article, a terahertz (THz) frequency quantum cascade laser with peak powers of > 1 W from a single facet in the pulsed mode is demonstrated.
Journal ArticleDOI
Ultrabroadband terahertz radiation from low-temperature-grown GaAs photoconductive emitters
TL;DR: Terahertz radiation was generated with a biased and asymmetrically excited low-temperature-grown GaAs photoconductive emitter, and characterized with a 20-μm-thick ZnTe crystal using free-space electro-optic sampling as mentioned in this paper.
Journal ArticleDOI
Temperature-dependent low-frequency vibrational spectra of purine and adenine
TL;DR: In this article, a number of well-resolved absorption peaks were observed in the frequency range 0.2-3.0 THz, which are interpreted as originating from intermolecular vibrational modes mediated by hydrogen bonds.
