We report a study of the structural phase transitions induced by pressure inbulk black phosphorus by using both synchrotron x-ray diffraction for pressuresup to 12.2 GPa and Raman spectroscopy up to 18.2 GPa. Very recently blackphosphorus attracted large attention because of the unique properties offewlayers samples (phosphorene), but some basic questions are still open in thecase of the bulk system. As concerning the presence of a Raman spectrum above10 GPa, which should not be observed in an elemental simple cubic system, wepropose a new explanation by attributing a key role to the non-hydrostaticconditions occurring in Raman experiments. Finally, a combined analysis ofRaman and XRD data allowed us to obtain quantitative information on presenceand extent of coexistences between different structural phases from ~5 up to~15 GPa. This information can have an important role in theoretical studies onpressure-induced structural and electronic phase transitions in blackphosphorus.
