Study of the Homology between Silicon and Germanium by Thermal-Neutron Spectrometry
Abstract
The phonon dispersion relations in silicon and germanium are found to be nearly homologous with small but significant deviations. These results, which have been obtained by thermal-neutron spectrometry, are strongly supported by an analysis in which comparison is made with elastic constants, heat capacities, and Raman frequencies for these elements. Previously observed discrepancies between results obtained from shell-model calculations and from heat-capacity measurements are explained. Attempts are made to elucidate the origin of the observed differences between the dimensionless phonon frequencies of group-IV $B$ elements with the diamond-type crystal structure.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
