The thermopower S of HgBa2Cam-1CumO2m+2+δ (Hg-12[m-1]m) has been investigated at various carrier concentration n and pressure P. At ambient pressure, S(290 K) changes with doping roughly following the proposed universal trend. S of Hg-1223 is nearly independent of P up to 1.6 GPa, suggesting a pressure-induced charged-transfer rate at least 10 times smaller than that of YBa2Cu3O7. The extreme small charge transfer present a challenge to some theoretical models.
