Measuring Fermi velocities with ARPES in narrow band systems. The case of layered cobaltates
V. Brouet, A. Nicolaou, M. Zacchigna +3
ARPES is a priori a technique of choice to measure the Fermi velocities vF in metals. In correlated systems, it is interesting to compare this experimental value to that obtained i…

Direct observation of strong correlations near the band insulator regime of Bi misfit cobaltates
V. Brouet, A. Nicolaou, M. Zacchigna +6
We present the first angle-resolved photoemission (ARPES) measurement of Fermi Surface in the "misfit" cobaltate [Bi2Ba2O4].[CoO2]~2. This compound contains the same triangular Co…
