Abstract: Combining (1) the universal correlations between Tc and ns/m∗ (superconducting carrier density/effective mass) and (2) the pseudo-gap behavior in the underdoped region, we obtain a picture to describe superconductivity in cuprate systems in evolution from Bose-Einstein to BCS condensation. Overdoped and Zn-substituted cuprate systems show signatures of reduced superfluid density in a microscopic phase separation. Scaling of Tc to the superfluid volume density ns in all these cases indicate importance of Bose condensation.
