Abstract:
The idea that the high-temperature superconductivity (HTSC) in cuprates originates in the copper-oxigen CuO2 layers was originally assumed on general theoretical grounds [1].
In the present paper we attempt a scrutiny of existing direct experimental evidence concerning the role of the CuO2 layers in the occurrence of the HTSC, which we have collected from 30 different references. Besides the interest of the discussion in itself, it is particularly important for the substantiation of the worthiness of the efforts toward the derivation of solutions of the two-dimensional two-band effective Hubbard model proposed by Plakida et al. [2] as the theoretical model able to provide a consistent explanation of the HTSC in cuprates.
