Helical Dirac-Majorana interferometer in a superconductor-topological insulator sandwich structure (1103.3425v2)
Published 17 Mar 2011 in cond-mat.mes-hall and cond-mat.supr-con
Abstract: In the heterostructure composed of a topological insulator sandwiched by two s-wave superconductors, the time reversal invariant topological superconducting phase, possessing helical Majorana edge modes, is found to exist when the two s-wave superconductors form a Josephson junction with a pi phase shift. Based on such a heterostructure, a helical Dirac-Majorana interferometer is proposed to directly measure a unique transport signature of the helical Majorana modes. Furthermore, we envision how our proposal can be realized on the basis of existing materials such as Bi2Se3 or Bi2Te3 thin films.
