a and b ρ(T) curves over the whole temperature and pressure range. Inset in a: characteristic temperatures of the two anomalies. Above 20 kbar, both anomalies seemingly disappear (or smear out). Inset in b: Development of the band gap with extrapolated fit. c Conductivity plots to demonstrate the VRH with \(\sigma \propto \exp {\left({T}_{0}/T\right)}^{1/4}\). The first anomaly is marked by small black arrows for two pressures. Inset: plot of the development of the anomaly under small magnetic fields at 13.81 kbar. d Conductivity plots to demonstrate \(\sigma \propto \sqrt{T}\). Again, the two anomalies are marked by arrows for one pressure. Inset: Plot of the conductivity at 16.22 kbar. The σ ∝ T1/3 law indicates critical behavior. e Magnetoconductance measurements at 500 mK for all pressures. In the lower and middle panel, curves are fitted by using the fitting function described by Eqs. (13) and (14).
