    • Charge-carrier behavior in Ba-, Sr- and Yb-filled CoSb3: NMR and transport studies 
      Tian, Yefan; Sirusi, Ali A.; Ballikaya, Sedat; Ghassemi, Nader; Uher, Ctirad; Ross, Joseph H. Jr. (2019)
      We report 59Co NMR and transport measurements on n-type filled skutterudites BaxYbyCo4Sb12 and AxCo4Sb12 (A=Ba or Sr), promising thermoelectric materials. The results demonstrate consistently that a shallow defect level ...
    • NMR Study of Ba8Cu5SixGe41-x Clathrate Semiconductors 
      Sirusi, Ali A.; Ross, Joseph H. Jr.; Yan, Xinlin; Paschen, Silke (Royal Society of Chemistry, 2015)
      We have performed 63Cu, 65Cu, and 137Ba NMR on Ba8Cu5SixGe41-x, a series of intermetallic clathrates known for their potential as thermoelectric materials, in order to investigate the electronic behavior of the samples. ...
    • Synthesis, transport and magnetic properties of Ba-Co-Ge clathrates 
      Sirusi, Ali A.; Ross, Joseph H. Jr. (Springer, 2016)
      Ba-Co-Ge intermetallic clathrates were synthesized in both type-I and chiral-type crystal structures to investigate thermoelectric and physical properties. Seebeck coefficients, thermal conductivities, electrical resistivities, ...
