摘要：

The pressure effect on the single-crystalline, nearly optimally doped high temperature cuprate superconductor YBa2Cu3O7-delta with a sharp ambient transition temperature of 90.7 K has been investigated resistively up to 29 GPa. An abrupt disappearance of superconductivity at 60 K under similar to 24 GPa was detected, accompanied by a thermally activated resistance, suggesting a possible pressure-induced superconducting-semiconducting transition. By comparing the present results with those of recent high pressure work on Bi2Sr2Ca2Cu3O10-delta, it is proposed that the control of such electronic instabilities may further help raise the superconducting transition temperature record of 164 K in tri-layer cuprate superconductors by pressures.
