文摘
- •
The 30-year history of “electron-doped” cuprates is reviewed, including basic physics and material issues.
- •
Undoped cuprates with the Nd2CuO4 (T’) structure are superconducting with Tc over 30 K.
- •
Electron doping by Ce in T’-RE2CuO4 lowers Tc and the highest Tc is obtained at no doping.
