Fig. 3: Temperature and pressure dependence of valence band edge.
From: Pressure-induced concomitant topological and metal-insulator quantum phase transitions in Ce3Pd3Bi4
a–e Temperature evolution of valence band edge Ev at 98%, 96%, 94%, 92%, and 90% of the equilibrium volume V0, respectively. The tops of the valence bands relative to the Fermi level are marked as blue (orange) dots. The gray dashed lines are linear fittings to Ev. The black arrow indicates the extrapolated critical temperatures T1 (marked as red dots) when the Ev cuts the Fermi level. f Pressure evolution of T1. The red dots mark T1 from (a–e). The blue dashed line is the linear extrapolation to zero temperature.
