ARPES Studies on $FeTe_{1-x}Se_{x}$

ORAL

Abstract

Angle-resolved Photoelctron Spectoscopy (ARPES) is used to study the electronic structure of Fe based superconductor, $FeTe_{1-x}Se_{x}$. Detailed comparisons are made between the measured Fermi surfaces and first principles FLAPW calculations. In particular we explore the origin of a Dirac like cone at the center of the Brillouin zone.
