Ideal strength of diamond, Si, and Ge
Abstract
We have calculated the ideal shear strength and ideal tensile strength of C, Si, and Ge in the diamond structure. We find ideal shear strengths of 95 GPa, 6.5 GPa, and 4.5 GPa, and ideal tensile strengths of 95 GPa, 23 GPa, and 14 GPa for C, Si and Ge respectively. The shear calculation is performed on the ${111}$ slip plane sheared in a $〈112〉$ direction, and the tensile load is applied in the $〈111〉$ direction. We allowed for a full relaxation of the strains orthogonal to the applied strain as well as the atomic basis vectors.

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.
