Phonon studies of the phase transition sequence in antiferroelectric single crystal of Pb(Hf0.83Sn0.17)O3
Anirudh K. R., Cosme Milesi-Brault, Christelle Kadlec +5
The sequence of phase transitions in PbHf0.83Sn0.17O3 has been studied by THz, far infrared and Raman spectroscopies, revealing the complementary behaviour of both, polar and non-p…
Phonon properties and unconventional heat transfer in quasi-2D crystal
Jan Zich, Antonín Sojka, Petr Levinský +10
Bi2O2Se belongs to a group of quasi-2D semiconductors that can replace silicon in future high-speed/low-power electronics. However, the correlation between crystal/band structure a…
Infrared, terahertz, and microwave spectroscopy of the soft and central modes in Pb(Mg1/3Nb2/3)O3
D. Nuzhnyy, J. Petzelt, V. Bovtun +4
From the new infrared (IR) reflectivity and time-domain terahertz (THz) spectra combined with available high-frequency dielectric data above the MHz range in a broad temperature ra…
Unusual ferroelectric and magnetic phases in multiferroic 2H-BaMnO ceramics
Stanislav Kamba, Dmitry Nuzhnyy, Maxim Savinov +16
The structural phase transition in hexagonal BaMnO occurring at =130 K was studied in ceramic samples using electron and X-ray diffraction, second harmonic generation as w…
Peculiar Bi-ion dynamics in Na1/2Bi1/2TiO3 from terahertz and microwave dielectric spectroscopy
Jan Petzelt, Dmitry Nuzhnyy, Viktor Bovtun +6
Dynamics of the main dielectric anomaly in Na1/2Bi1/2TiO3 (NBT) was studied by time-domain THz and microwave spectroscopy, using also previously published data and their new overal…
Broadband dielectric spectroscopy of Ba(Zr,Ti)O3: dynamics of relaxors and diffuse ferroelectrics
J. Petzelt, D. Nuzhnyy, M. Savinov +6
Broadband dielectric spectroscopy from Hz up to the infrared (IR) range and temperature interval 10-300 K was carried out for xBaZrO3-(1-x)BaTiO3 (BZT-x, x = 0.6, 0.7, 0.8) solid s…
