我们利用核心级 X 射线光电子能谱推导出了高超导体中的化学势位移。导出的结果是刚性带状的，并且空穴浓度几乎是线性的，与最近的角分辨光电子能谱研究估计的位移在数量上一致。此外，ini 比 (LSCO) 中的大得多，并且与 (LSCO) 中的一样大。根据电荷排序的不同行为，讨论了 和 LSCO 之间的定性不同行为。
We have deduced the chemical potential shiftin the high-superconductorusing core-level x-ray photoemission spectroscopy. The derivedis rigid-band-like, and almost linear in hole concentration, quantitatively consistent with the shift estimated from a recent angle resolved photoemission spectroscopy study. Also,inis much larger than that in(LSCO) and as large as that in. Qualitatively different behavior ofbetweenand LSCO is discussed in relation to the different behaviors of charge ordering.
