Persistent Octahedral Coordination in Amorphous GeO_{2} Up to 100 GPa by Kβ^{′′} X-Ray Emission Spectroscopy

Persistent Octahedral Coordination in Amorphous GeO_{2} Up to 100 GPa by Kβ^{′′} X-Ray Emission Spectroscopy

We measure valence-to-core x-ray emission spectra of compressed crystalline GeO_{2} up to 56 GPa and of amorphous GeO_{2} up to 100 GPa. In a novel approach, we extract the Ge coordination number and mean Ge-O distances from the emission energy and the intensity of the Kβ^{′′} emission line. The spe...
