High Pressure

Raman spectroscopy

Raman spectroscopy is a powerful method to study the pressure effect on interatomic interactions in the materials, to monitor pressure induced phase transitions, and in combination with high-pressure synchrotron x-ray diffraction, to determine the structures of the new polymorph forms of matter. Currently we are studying pressure induced structural phase transitions and pressure effect on the electronic properties of the alkali hyper- and sesqui-oxides.
