Extended superconducting dome of electron-doped cuprates after protect annealing revealed by ARPES

The electron-doped cuprates are usually characterized by a more robust antiferromagnetic phase and a much narrower superconducting (SC) dome than those of the hole-doped counterparts. Recently, bulk single crystals of Pr1.3-xLa0.7CexCuO4 (PLCCO) prepared by the protect annealing method have been studied extensively and revealed many intriguing properties that were different...
