Majorana fermion(MF),an exotic particle that is identical to its own antiparticle,was recently found in solid matter as a quasiparticle excitation,the Majorana zero mode(MZM),in the vortex of an artificial topological superconductor(TSC).This artificial TSC,first proposed by Fu and Kane in 2008,is a heterostructure made of a topological insulator Bi_2Te_3 and an s-wave superconductor NbSe_2.This paper will briefly review the experimental progresses based on the Bi_2Te_3/NbSe_2 heterostructure.All evidences are self-consistent and reveal that the MZM exists in the center of vortex.Those experimental results are also supported by theory.This finding is a milestone in the research of Majorana fermions in solid state physics and a starting point of MZM’s application in topological quantum computation.
