We have studied the chemical potential shift and changes in the electronic density of states near the Fermi level $({E}_{F})$ as a function of carrier concentration in ${\mathrm{Pr}}_{1\ensuremath{-}x}{\mathrm{Ca}}_{x}\mathrm{Mn}{\mathrm{O}}_{3}$ (PCMO, $0.2\ensuremath{\leqslant}x\ensuremath{\leqslant}0.65$) through the measurements of photoemission spectra. The results showed that the chemical potential shift was suppressed for $x\ensuremath{\gtrsim}0.3$, where the …
