Nonetheless, a large contribution of the bulk conduction, induced by unintended doping by defects, has hindered the characterization of the unique surface state and the utilization of it into a device. To resolve this problem, we have investigated the transport properties of epitaxial Bi2-xSnxTe3 thin films with varying x.
