摘要：
The hypothesis of charge-transfer to the cuprate-planes, which lies at the foundation for most theories on high-temperature superconductivity, is re-examined in light of recent neutron-diffraction data for La2-betaSrbetaCuO4 and Nd2-zCezCuO4. The data indicate that the cuprate-planes do not acquire holes as the materials become superconducting, and that the superconducting p-type regions of the unit cells are in the noncuprate-plane charge-reservoir layers instead.
