Thre-Dimensional Fermi Surface of Overdoped La-based Cuprates

POSTER

Abstract

On this poster, we present a soft x-ray angle-resolved photoemission spectroscpoy study of the high-temperature superconductors La2-xSrxCuO4 (LSCO) and La1.8-xEu0.2SrxCuO4.Mapping in-plane and out-of-plane components of the Fermi surface reveals a distinct kz-dispersion, that was parametrizing a tight binding model [1]. In this fashion, we quantify the contribution of the van Hove singularity to specific heat found in over doped LSCO can't be assigned to the van Hove singularity and is theefore taken as evidence of quantum criticality.
