Effect of electron irradiation of ZnGeP2 single crystals on terahertz losses in a wide temperature range
by S. V. Chuchupal, G. A. Komandin, E. S. Zhukova, O. E. Porodinkov, I. E. Spektor, A. I. Gribenyukov
The reflection and transmission spectra of ZnGeP₂ single crystals irradiated with 4-MeV electrons have been measured in the frequency range of 5-5000 cm⁻¹ at temperatures in the range of 10-300 K. Based on the measured spectra, the spectra of complex permittivity ɛ*(ν) and absorption coefficient α(ν) have been simulated using the dispersion analysis method. It has been found that the electron irradiation decreasing the losses in the pumping range by a factor of 2–3 does not lead to additional losses in the region of generating terahertz radiation.

Dielectric response of (Ba,Sr)TiO3 thin films in a terahertz and IR ranges
by G. A. Komandin, V. M. Mukhortov, O. E. Porodinkov, I. E. Spektor
Dependences of the dielectric response spectra on the thickness of the films based on the (Ba,Sr)TiO₃ (BST) solid solutions, which were deposited on single-crystal MgO substrates, have been analyzed. Using the Lorentz and Lyddane-Sachs-Teller models, the mutual correspondence of longitudinal optical (LO) and transverse optical (TO) phonon frequencies has established. The giant LO-TO splitting of the lowest-frequency vibration and inversion of LO and TO frequencies of other phonons in the IR spectrum of BST films has been found for the first time.
