Figure 4

Bi-III/Bi-V transition pressure as a function of compression rate for different sample types (foil and powder) and different sample conditions (with and without a PTM). The transition is identified by the first appearance of Bi-V in the diffraction patterns, as described in the text. The solid lines show a fit of the dynamic compression data to functional form y=Alogx+B, and the resultant fit parameters are given in Table S2.
