| Abstract Scope |
One of the most important properties of the topological insulators is the existence of conducting surface states within the bulk band gap. The surface states of a three-dimensional (3D) topological insulator consist of an odd number of massless Dirac cone. Here, we present the spectroscopic, magnetic, thermodynamic, and transport results of Gadolinium substituted Sb2Te3 crystal. By using Angle Resolved Photoemission Spectroscopy (ARPES), our study demonstrates the electronic structure of the layered GdxSb2-xTe3, where we observe the surface states consist of a single Dirac cone at the zone center. In addition, we measure the temperature and magnetic field dependent electrical resistivity, magnetization, thermal conductivity, and heat capacity of GdxSb2-xTe3. Thus, by combining surface and bulk measurements, we were able to reveal the degree of correlation of 4f electrons and its effect on the electronic properties (structure and transport) in this material. |
