Substrate-controlled epitaxial-like growth of photochromic yttrium oxyhydride thin films
M. Zubkins, E. Strods, E. Letko +7
Yttrium oxyhydride (YHO) thin films are synthesised by reactive magnetron sputtering of \b{eta}-YHx precursor films onto single-crystalline yttria-stabilised zirconia (YSZ) (111) a…
Hydrogen partial pressure as a key parameter in the reactive sputtering of photochromic YHO thin films
E. Strods, M. Zubkins, E. Letko +3
Oxygen-containing yttrium hydride (YHO) thin films were synthesised by reactive magnetron sputtering over a wide range of hydrogen-to-argon gas flow ratios (H2/Ar) during yttrium h…
Impact of interstitial carbon on local lattice distortions in CoCrFeMnNi high-entropy alloys
Alevtina Smekhova, Alexei Kuzmin, G. Mohan Muralikrishna +5
Here, we explore component-dependent local lattice distortions in polycrystalline, equiatomic, face-centered cubic CrMnFeCoNi high-entropy alloys and their modifications induced by…
Local lattice dynamics of hcp zinc from EXAFS and machine-learning interatomic potentials
Vitalijs Dimitrijevs, Pjotrs Žguns, Inga Pudza +2
The lattice dynamics of hexagonal close-packed (hcp) zinc, a prototypical anisotropic metal, is studied using temperature-dependent Zn K-edge extended X-ray absorption fine structu…
Growth and characterization of GaN/Ga2O3 Nanowire Heterostructures for Ultraviolet Optoelectronics
Edgars Butanovs, Eriks Dipans, Martins Zubkins +10
Ultraviolet-range GaN/b-Ga2O3 heterostructures were fabricated and investigated in both planar and nanowire geometries using pulsed laser deposition and reactive magnetron sputteri…
Ytterbium charge state and stabilization in the Ba(Ca)F host by electron paramagnetic resonance and infrared photoluminescence
David John, Shelja Sharma, Marius Stef +18
Lanthanide-doped fluorides are promising materials for advanced photonic and quantum applications due to their wide bandgap, low phonon energy, and chemical stability. In this work…
