Gap-opening transition in Dirac semimetal ZrTe
Yefan Tian, Nader Ghassemi, Joseph H. Ross
We apply Te nuclear magnetic resonance (NMR) spectroscopy to investigate the Dirac semimetal ZrTe. With the NMR magnetic field parallel to the -axis, we observe sign…
Topological nodal line in ZrTe demonstrated by nuclear magnetic resonance
Yefan Tian, Nader Ghassemi, Joseph H. Ross
In this work, we report nuclear magnetic resonance (NMR) combined with density functional theory (DFT) studies of the transition metal dichalcogenide ZrTe. The measured NMR shi…
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…
