Abstract
We conducted high pressure measurements on the graphitic C3N4 (g-C3N4) phase using Brillouin light scattering (BLS) up to 41.5 GPa and X-ray Raman scattering (XRS) up to 26 GPa to probe the behavior of sp2 bonds. Analysis of the BLS and XRS measurements of g-C3N4 reveals no structural phase transition and, unlike graphite, no sp2 to sp3 rehybridization in this pressure range. From the BLS results we estimate the ambient condition longitudinal velocity (VL = 6.27 ± 0.12 km/s), aggregate shear wave velocity (VS = 3.04 ± 0.2 km/s), and the shear (μ = 21.6 GPa) and bulk elastic moduli (KV = 63.1 GPa) of the g-C3N4.
