Variation of the $^{13}$C diamond properties under isothermal compression
M. N. Magomedov Institute of Geothermy Problems, Makhachkala
Abstract:
The parameters of atomic interaction pair potential for $^{13}$C diamond have been determined from experimental data on the ratio of Raman frequencies for isotopically different diamonds. Based on these parameters, an equation of state and baric dependences of $^{13}$C diamond lattice properties at 300 K have been calculated. Specifically, the Debye temperature; the first, second, and third Grüneisen parameters; elastic modulus; thermal expansion coefficient; heat capacity; surface energy; and pressure derivatives of these parameters along a 300 K isotherm have been determined. The results have been compared with available data for diamond having a natural isotopic composition, i.e., for $^{12.01}$C.
