      Anharmonic guest atom oscillation has direct connection to the thermal transport and thermoelectric behavior of type-I Ba8Ga16Sn30 clathrates. This behavior can be observed through several physical properties, with for ...
    • Sergio Y., Rodriguez; Saribaev, Laziz; Ross, Joseph H. Jr. (American Physical Society, 2010)
      In a study of type-I Ba8AlxGe46−x clathrates for 4≤x≤16, several samples with different stoichiometric compositions were prepared and measured. Here we report wavelength dispersion spectroscopy, powder x-ray diffraction ...
