New electronic orderings observed in cobaltates under the influence of misfit periodicities
A. Nicolaou, V. Brouet, M. Zacchigna +10
We study with ARPES the electronic structure of CoO2 slabs, stacked with rock-salt (RS) layers exhibiting a different (misfit) periodicity. Fermi Surfaces (FS) in phases with diffe…

Experimental study of the incoherent spectral weight in the photoemission spectra of the misfit cobaltate [Bi2Ba2O4][CoO2]2
A. Nicolaou, V. Brouet, M. Zacchigna +8
Previous ARPES experiments in NaxCoO2 reported both a strongly renormalized bandwidth near the Fermi level and moderately renormalized Fermi velocities, leaving it unclear whether…
