Where are the electrons near Fermi Surface spatially distributed in HTS

In summary, the wave functions of electrons near the Fermi surface are typically distributed across both active and charge-reservoir blocks in most materials. However, the exact distribution may vary depending on the specific material and type of wave function.

Namely, are the wave functions of electrons near the Fermi surface spatially distributed in the so-called "active blocks" (CuO2 layers and etc.) or in the so-called "charge reservoir blocks" ? Or any other case?

( EO/(AOx)m/EO with m =1, 2 monolayers of a quite arbitrary oxide AOx(A = Bi, Pb, Tl, Hg, Au, Cu, Ca, B, Al, Ga)

Is there any known conclusion/result on this?

Thanks.

The answer to this question depends on the specific material in question and the type of electron wave function being considered. In general, electrons near the Fermi surface are usually distributed across multiple blocks, including both active and charge-reservoir blocks. For example, in a layered material such as copper oxide, the wave functions of electrons near the Fermi surface may be distributed across the CuO2 layers as well as the layers of other compounds (such as BiOx and TlOx). Similarly, in a three-dimensional material such as aluminum oxide, the wave functions may be distributed across the active block (AlOx) and the charge-reservoir blocks (EO/(AOx)m/EO with m = 1, 2 monolayers of a quite arbitrary oxide AOx (A = Bi, Pb, Tl, Hg, Au, Cu, Ca, B, Al, Ga). Ultimately, the exact distribution of electronic wave functions near the Fermi surface will depend on the specific material and the type of wave function being considered.
