N2 - We have studied the chemical potential shift in the electron-doped superconductor (formula presented) by precise measurements of core-level photoemission spectra. The result shows that the chemical potential monotonously increases with electron doping, quite differently from (formula presented) where the shift is suppressed in the underdoped region. If the suppression of the shift in (formula presented) is attributed to strong stripe fluctuations, the monotonous increase of the chemical potential is consistent with the absence of stripe fluctuations in (formula presented) The chemical potential jump between (formula presented) and (formula presented) is suggested to be much smaller than the optical band gaps.
