|A critical review of previous investigations of the superconductivity with enhanced
Tc of 100 K found in Sr2CuO4-v shows that new physics occurs in a highly overdoped
region of the cuprate phase diagram. Moreover, evidence is adduced from the
literature that 30% of the oxygen sites in the CuO2 layers are vacant; a conclusion
that is at odds with the universally made assumption that superconductivity originates
in stoichiometric CuO2 layers.
Possible models will be discussed.
