Description
The temperature dependence of the hole concentration in high-temperature superconductors is considered in terms of the model of negative-U centers. It is shown that this dependence can be nonmonotonic due to the interaction of electron subsystems from the valence band with negative-U centers and the conditions necessary for this have been established. The results obtained are compared with experimental data on the Hall coefficient in cuprates
