Ramp Compression of Germanium Dioxide to Extreme Conditions: Phase Transitions in an SiO_{2} Analog

The high-pressure (HP) behavior of dioxides is of interest due to their extensive polymorphism and role as analogs for SiO_{2}, a phase expected to be important in the deep mantles of Earth and terrestrial exoplanets. Here we report on dynamic ramp compression of quartz-type germanium dioxide GeO_{2...
