| 英文摘要 | Here we report the in situ high-pressure (up to similar to 50-GPa) Hall-effect measurements on single-crystal black phosphorus. We find a strong correlation between the sign of the Hall coefficient, an indicator of the dominant carrier type, and the superconducting transition temperature (T-C). Importantly, we find a change from electron-dominant to hole-dominant carriers in the simple cubic phase of phosphorus at a pressure of similar to 17.2GPa, providing an explanation for the puzzling valley it displays in its superconducting T-C vs pressure phase diagram. Our results reveal that hole carriers play an important role in developing superconductivity in elemental phosphorus and the valley in T-C at 18.8 GPa is associated with a Lifshitz transition. |
