Abstract

The 3D Fermi-surface (FS) mapping of Bi2Se3 for different samples with carrier-density ranging from 1017 to 1020 cm-3 was made using Angle Resolved Photoemission Spectroscopy. While in the low carrier density samples a closed FS was observed, in high carrier density superconducting CuxBi2Se3 samples the FS was found to be open. The open FS puts constraints on the possible order-parameters in this system.
