Temperature-dependent gap opening in doped graphene

ORAL

Abstract

Fundamental physical properties of a material are strongly affected by electronic correlations, which typically reveal their origins through a temperature-dependence study. By using angle-resolved photoemission spectroscopy, we study unusual gap opening in doped graphene as a function of temperature, which poses a strong constraint on the charge carrier scattering mechanism in this system. Our finding provides a potentiality to realize new correlated states with unusual properties.
