HP-XRD results and the high-pressure structure of TaP. a The high-pressure x-ray diffraction of TaP up to 101.66 GPa. The red dashed lines highlight the evolution of some selected peaks. b Relative diffraction intensity of four selected peaks normalized by that of the (112) peak vs. applied pressures. c The emergence of (021) peak belonging to the P-6m2 structure when the pressure exceeds 71.08 GPa (green line), which clearly indicates the structure phase transition. d Crystal structures of I41 md and P-6m2 phases (elaborated using the VESTA software39). TaP adopts I41 md space group at ambient pressure and transforms to P-6m2 at about 70 GPa. This high-pressure phase can be reserved after external pressure released. e XRD data after decompressing (symbols) and the fitting result using the P-6m2 structure (black solid line)
