    • A Cd-S bond length expansion of 0.003 A between 5 and 290 K calculated from the bulk thermal expansion was taken into account.

    • More precisely, EXAFS measures predominantly the projection of the thermal vibrations along the bond direction.

    • This was verified by X-ray diffraction at room temperature. The derived lattice constants for the original hexagonal CdS powder agree with literature within 0.001 Å (ref 45), whereas the pressed samples show slightly lowered parameters.

    • note
    • This is consistent with the observation that a similar EXAFS data analysis as presented in this study on Cd K edge spectra of cubic CdTe bulk at 8 K shows in comparison to hexagonal CdS bulk a significantiy reduced anharmonicity of the interatomic potential.
