High-pressure elastic properties of GeO2 polymorphs up to 120 GPa
Gulshan Kumar, Sumit Ghosh, Sharad Babu Pillai +1
We systematically investigated the phase stability and pressure dependence of the elastic properties of four GeO2 polymorphs: rutile-, CaCl2-, alpha-PbO2-, and pyrite-type phases u…

High-pressure Phase Transition of Olivine-type MgGeO to a Metastable Forsterite-III type Structure and their Equation of States
R. V. Divya, G. Kumar, R. E. Cohen +5
Germanates are often used as structural analogs of planetary silicates. We have explored the high-pressure phase relations in MgGeO using diamond anvil cell experiments com…
