Half-Heusler thermoelectric materials: NMR studies
Yefan Tian, Nader Ghassemi, Wuyang Ren +6
We report Co, Nb, and Sb nuclear magnetic resonance (NMR) measurements combined with density functional theory (DFT) calculations on a series of half-Heusler…
Defect charging and resonant levels in half-Heusler NbTiFeSb
Yefan Tian, Farit G. Vagizov, Nader Ghassemi +5
We report Nb and Sb NMR and Fe Mössbauer studies combined with DFT calculations of NbTiFeSb (), one of the most promisi…
Copper ion dynamics and phase segregation in Cu-rich tetrahedrite: an NMR study
Nader Ghassemi, Yefan Tian, Xu Lu +3
Cu NMR measurements are reported for the Cu-rich phase of \ch{Cu_{12+x}Sb4S13} () and compared to \ch{Cu12Sb4S13}. We identify the NMR signatures of the phase…
Charge-carrier behavior in Ba-, Sr- and Yb-filled CoSb: NMR and transport studies
Yefan Tian, Ali A. Sirusi, Sedat Ballikaya +3
We report Co NMR and transport measurements on -type filled skutterudites BaYbCoSb and CoSb (= Ba, Sr), promising thermoelectric m…
Dirac electron behavior and NMR evidence for topological band inversion in ZrTe5
Yefan Tian, Nader Ghassemi, Joseph H. Ross
We report Te NMR measurements of the topological quantum material ZrTe. Spin-lattice relaxation results, well-explained by a theoretical model of Dirac electron systems…
