摘要：
The elastic constants of alpha-GeO2, the quartzlike polymorph of germanium dioxide, have been determined using Brillouin scattering. The data were obtained using a high quality single crystal of alpha-GeO2. When compared with existing data on alpha-SiO2, our results show that the shear constants are considerably softened in GeO2. This could be an indication that the observed pressure induced phase change is related to a shear instability. (C) 1998 American Institute of Physics.
