Symmetry breaking in single crystal SrTiO plates: EPR manifestations
Bulat F. Gabbasov, Irina N. Gracheva, Alexander A. Rodionov +6
Electron paramagnetic resonance studies of the impurity Fe and Mn centers indicate that the symmetry of the crystal structure of millimeter-scale strontium titanate p…
Two modes of HVPE growth of GaN and related macrodefects
V. V. Voronenkov, N. I. Bochkareva, R. I. Gorbunov +9
GaN films with thickness up to 3 mm were grown by halide vapour phase epitaxy method. Two growth modes were observed: the high temperature (HT) mode and the low temperature (LT) mo…
Viscosity of Cobalt Melt: Experiment, Simulation, and Theory
R. M. Khusnutdinoff, A. V. Mokshin, A. L. Bel'tyukov +1
The results of experimental measurements, molecular dynamics simulation, and theoretical calculations of the viscosity of a cobalt melt in a temperature range of ~K at a…
High resolution resonant inelastic EUV scattering from orbital excitations in a Heisenberg antiferromagnet
Antonio Caretta, Martina Dell'Angela, Yi-De Chuang +11
We report the high resolution resonant inelastic EUV scattering study of quantum Heisenberg antiferromagnet KCoF3. By tuning the EUV photon energy to cobalt M23 edge, a complete se…
Optical thermometry based on level anticrossing in silicon carbide
A. N. Anisimov, D. Simin, V. A. Soltamov +4
We report a giant thermal shift of MHz/K related to the excited-state zero-field splitting in the silicon vacancy centers in 4H silicon carbide. It is obtained from the ind…
Dual Optical Marker Raman Characterization of Strained GaN-channels on AlN Using AlN/GaN/AlN Quantum Wells and 15N Isotopes
Meng Qi, Guowang Li, Vladimir Protasenko +10
This work shows that the combination of ultrathin highly strained GaN quantum wells embedded in an AlN matrix, with controlled isotopic concentrations of Nitrogen enables a dual ma…
