Dynamic compression of Bi. (a) Integrated XRD data as a function of time. (b) Selected integrated patterns illustrating the pressure-induced Bi-III/Bi-V structural phase transition. (c) Voltage applied to the piezo actuator and sample pressure as a function of time. In (a), the reflections from Bi-III, which has a host–guest structure, are identified using four Miller indices (hklm) (McMahon et al., 2007). In (c), PBi was determined using the EoS of Bi-V (Degtyareva et al., 2004) and PCu was determined using the EoS of Cu (Dewaele et al., 2004). The intensity of the Cu (111) reflection was very weak, and so PCu was determined from the sum of six consecutive diffraction images. |
