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…
Scalable solution chemical synthesis and comprehensive analysis of Bi2Te3 and Sb2Te3
Bejan Hamawandi, Parva Parsa, Inga Pudza +7
Thermoelectric (TE) materials can directly convert heat into electrical energy. However, they sustain costly production procedures and batch-to-batch performance variations. Theref…
The use of the correlated Debye model for EXAFS-based thermometry in bcc and fcc metals
Alexei Kuzmin, Vitalijs Dimitrijevs, Inga Pudza +1
Extended X-ray absorption fine structure (EXAFS) spectra are sensitive to thermal disorder and are often used to probe local lattice dynamics. Variations in interatomic distances i…
