摘要: The present work provides a comprehensive compilation and discussion covering hardness, experimentally determined elastic properties, thermal expansion, Debye Einstein temperatures for intermetallic clathrates. Comparing hardness values properties major influence of the framework atoms is observed. Hardness moduli change linearly with Si/Ge-ratio. Also linear temperature dependence In case that vacancies are in clathrate framework, different compounds decreases almost an increasing vacancy-content. As significance vibrational spectra performance thermoelectric materials, corresponding extracted from various measurement techniques such as sound velocity, specific heat, electrical resistivity or X-ray absorption diffraction measurements evaluated. correlate melting clathrates, similar guest show on cage size. Wherever available, experimental data compared those DFT model simulations. general derived match theoretically calculated.
