Abstract
A molecular dynamic (MD) simulation with a new potential model has been performed to investigate the structural change of germanium dioxide under high pressure. A phase transition of α-quartz-type GeO2 crystal was found over 6.0 GPa at 300 K. This transformation involves an abrupt volume shrinkage according to the increase of the coordination number of germanium. It is shown that the MD simulation results are in good agreement with the experiment.
