Spectra for cgN. (IMAGE)
Caption
The Raman spectra show new peaks at 635 cm-1 and 700 cm-1 that characterize the formation of cg-N. Inset shows the pressure dependence of Raman fingerprint peak position for cg-N, including the experimental detected at 110 GPa (solid circle) [Eremets M. I. et. al. Nat. Mater., 3, 558 (2004)] and the calculated vibrational position at 35 GPa (open circle) [Caracas R. et al. J. Chem. Phys., 127, 14451053 (2007)] of cg-N by the A mode extracted that can be extrapolated linearly to ambient pressure as shown by the dashed line.
