Surface state bi-polarons formation on a triangular lattice in the sp-type alkali/Si(111) Mott insulator
L. A. Cardenas, Y. Fagot-Revurat, L. Moreau +2
We report on new LEED, STM and ARPES studies of alkali/Si(111) previously established as having a Mott insulating ground state at surface. The observation of a strong temperature d…

Anomalous spectral weight in photoemission spectra of the hole doped Haldane chain Y2-xSrxBaNiO5
Y. Fagot-Revurat, D. Malterre, F. X. Lannuzel +4
In this paper, we present photoemission experiments on the hole doped Haldane chain compound . By using the photon energy dependence of the photoemission cross…
