Direct measurement of molecular mobility and crystallisation of amorphous pharmaceuticals using terahertz spectroscopy. [PDF]
, 2016 Despite much effort in the area, no comprehensive understanding of the formation and behaviour of amorphous solids has yet been achieved. This severely limits the industrial application of such materials, including drug delivery where, in principle ...

Sub-terahertz and terahertz generation in long-wavelength quantum cascade lasers
Nanophotonics, 2019 Terahertz quantum cascade laser sources with intra-cavity non-linear frequency mixing are the first room-temperature electrically pumped monolithic semiconductor sources that operate in the 1.2–5.9 THz spectral range.

Nonlinear Terahertz Emission in Semiconductor Microcavities [PDF]
, 2013 We consider the nonlinear terahertz emission by the system of cavity polaritons in the regime of polariton lasing. To account for the quantum nature of terahertz-polariton coupling we use the Lindblad master equation approach and demonstrate that quantum

MATCHING STRUCTURES WITH FORM BIREFRINGENCE WITH FREE SPACE IN THZ RANGE [PDF]
Радиофизика и электроника, 2015 When constructing polarization radio measuring paths operating in the THz frequency range (0.1…10 THz) the differential phase sections (DPS) are widely used. The use of terahertz waves (THz) allows research in radio astronomy, radio spectroscopy, biology,

Thermal Radiation from Carbon Nanotubes in the Terahertz Range [PDF]
Physical Review Letters, 2007 The thermal radiation from an isolated finite-length carbon nanotube (CNT) is theoretically investigated both in near- and far-field zones. The formation of the discrete spectrum in metallic CNTs in the terahertz range is demonstrated due to the reflection of strongly slowed-down surface-plasmon modes from CNT ends.

PROSPECTS OF THE USE OF GRADIENT GRATES IN THE LASERS OF TERAHERTZ RANGE [PDF]
Radio Physics and Radio Astronomy, 2018 Purpose: The improvement and development of terahertz radiation sources is required for the further development of the terahertz frequency range. Submillimeter lasers are one of the few sources of terahertz radiation.
