Ultrastable phonon frequencies in alpha-quartz-type BPO4 at high temperature
Original language description
The Raman modes of alfa-quartz-type boron phosphate were found to be extremely stable in frequency over a large temperature range from 300-1000K. In order to determine the origin of this behavior, the material was also studied at high pressure up to 6 GPa. Upon compression, a classical behavior was observed with mode Grüneisen parameters ranging from -0.08(2) to 3.0(1). The present results indicate that the high temperature behavior in this material is an example of an unusual compensation effect between phonon-phonon interactions and implicit contributions due to thermal expansion.
