Brillouin scattering in diamond
M. H. Grimsditch,A. K. Ramdas +1 more
TL;DR: In this paper, the Brillouin spectrum of diamond excited with either the arXiv:1708.1640$ or He-Ne laser radiation was measured with a triple-passed piezoelectrically scanned Fabry-Perot interferometer.

A revised diamond-graphite transition curve
TL;DR: In this paper, a revised curve based on a critical review of the experimental and thermodynamic data is consistent with expanded experimental brackets and the preferred calorimetric data, and the revised curve implies that the minimum pressure for formation of diamond-bearing crustal rocks is 3-4 kbar less than implied by extrapolation of the experiments.

The Four Elastic Constants of Diamond
TL;DR: In this article, the authors evaluated the elastic constants of diamond directly from the observed frequency shifts and found that McSkimin and Bond's values do not agree with those of Bhagavantam and Bhimasenachar and of Prince and Wooster, especially as regards C12 and C44.
