Ce doping in T-La2CuO4 films: Broken electron-hole symmetry for high-Tc superconductivity

A. Tsukada, H. Yamamoto, M. Naito

We attempted Ce doping in La2CuO4 with the K2NiF4 (T) structure by molecular beam epitaxy. At low growth temperature and with an appropriate substrate choice, we found that Ce can…
