Electron Number-Based Phase Diagram of Pr sub(1-x) LaCe sub(x) CuO sub(4-[delta]) and Possible Absence of Disparity between Electron- and Hole-Doped Cuprate Phase Diagrams
We performed annealing and angle resolved photoemission spectroscopy studies on electron-doped cuprate Pr sub(1-x) LaCe sub(x) CuO sub(4-[delta])(PLCCO). It is found that the optimal annealing condition is dependent on the Ce content x. The electron number (n) is estimated from the experimentally ob...

| description | We performed annealing and angle resolved photoemission spectroscopy studies on electron-doped cuprate Pr sub(1-x) LaCe sub(x) CuO sub(4-[delta])(PLCCO). It is found that the optimal annealing condition is dependent on the Ce content x. The electron number (n) is estimated from the experimentally obtained Fermi surface volume for x= 0.10, 0.15 and 0.18 samples. It clearly shows a significant and annealing dependent deviation from the nominal x. In addition, we observe that the pseudo-gap at hot spots is also closely correlated with n; the pseudogap gradually closes as n increases. We established a new phase diagram of PLCCO as a function of n. Different from the x-based one, the new phase diagram shows similar antiferromagnetic and superconducting phases to those of hole doped ones. Our results raise a possibility for absence of disparity between the phase diagrams of electron- and hole-doped cuprates |
