Figure 3

(a,b) Hole doping level (Δp) dependence of Tc in Hg1212 (a) and Hg1223 (b) at ambient pressure (filled circle and solid line) and 12 GPa (open circle and dashed line ). Areas filled with pink and green show Tc -increased and—decreased, respectively, with pressure. (c,d) Measured and interpolated values of Tc as a function of Δp for Hg1212 (c) and Hg1223 (d) at high pressures. The parabolic solid lines show the fitting for the constant-pressure Tc versus Δp curves. Colour of the line and circle corresponds to the text colour of the pressure. (e,f) Pressure (P) dependence of Tc maximum (blue square) and Δp (red circle) that provides Tc maximum for Hg1212 (e) and Hg1223 (f). These values are estimated by the fitting curves of panel (c,d). (g,h) Tc contour maps on pressure doping level (P–Δp) diagram in Hg1212 (e) and Hg1223 (f). A colour bar shows Tc value in Kelvin. The dots in pale pink correspond to the measured data points.
