Abstract

A new method is presented for measuring thermal or structural disorder. The additional disorder in the first Ge-O and Ge-Ge distances in amorphous GeO2 was measured by comparison with crystalline (-quartz) GeO2, and showed no additional disorder in the Ge-O distances but deviations in the Ge-Ge distance consistent with a 6.5° variation about a Ge-O-Ge bond angle of 130°. These results rule out the proposed microcrystalline models.
