We consider the problem of the charge distribution of holes among the various CuO2 layers in the unit cell for compounds of the type Tl2Ba2Can−1CunO2n+4. In analogy with graphite intercalation compounds, the charge distribution is strongly nonhomogeneous (for n≥3) with a depletion in the central layers. This result points to a special importance of the bounding layers and it provides a way to understand the observed maximum Tc as a function of n.

Abstract
We consider the problem of the charge distribution of holes among the various CuO2 layers in the unit cell for compounds of the type Tl2Ba2Can−1CunO2n+4. In analogy with graphite intercalation compounds, the charge distribution is strongly nonhomogeneous (for n≥3) with a depletion in the central layers. This result points to a special importance of the bounding layers and it provides a way to understand the observed maximum Tc as a function of n.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
