Detection of acoustic phonons in carbon by Raman spectroscopy
Konstantin Iakoubovskii, Andrey Katrusha, Weihua Peng +1
We detected acoustic phonons in graphite and diamond by Raman spectroscopy supported by density functional theory calculations. The activation of these normally forbidden Raman mod…
Optical centers in cubic boron nitride and diamond: remarkable similarities
Konstantin Iakoubovskii, Andrey Katrusha, Weihua Peng +1
We present a comparative study of optical absorption and luminescence from cubic boron nitride (cBN) and diamond grown by the high-pressure high-temperature technique in the same c…
Dispersion models describing coupled systems in doped crystals. II. Infrared phonon excitations in GaAs single crystals and phonon-plasmon coupling in Zn-doped GaAs
Daniel Franta, Beata Hroncova, Mihai-George Muresan +1
We present a temperature-dependent infrared study of intrinsic and Zn-doped GaAs within a generalized dispersion framework describing coupled phonon and free-carrier excitations. R…
A high-dimensional neural network potential for finite-temperature phenomena in NiTi martensite
Petr Jaroš, Petr Sedlák, Petr Šesták +3
We present a high-dimensional neural network potential (HDNNP) for the martensitic phase of the NiTi shape-memory alloy trained to density functional theory (DFT) data. A central a…
Comparison of two laser wavelengths for LIBS bioimaging of plants grown in lunar regolith
T. Vozár, L. Čechová, J. Buday +8
The colonisation of extraterrestrial planets requires sustainable food production independent of Earth-based supplies. Due to the high costs and complicated logistics of food trans…
Plasmonics of non-noble metals
Michal Horák, Michael Foltýn, Viktor Bajo +2
Localized surface plasmon resonances are self-sustained, collective oscillations of free electrons in metallic nanostructures. They have a wide range of applications. The most comm…
