Abstract

Reasonably good agreement with pressure-induced changes of hole concentration in Tl₂Ba₂CuO_6+δ compounds can be obtained on the basis of a pressure-induced charge transfer model. The calculated pressure derivative of maximum T_c of 0.87 K/GPa within the van Hove singularity scenario and the predicted variation of T_c with pressure in bilayer Tl₂Ba₂CaCu₂O₈ are in excellent agreement with experiments.
