Majorana particle or Majorana fermion (MF) at its exotic state is its anti-particle may be beneficial as a qubit for topological quantum computing. We report experimental observations of Majorana fermions at their zero-energy bound state by using a topological superconductor-insulator- normal metal (SIN) configured device, which has an organo- metallic superlattice membrane with arrays of flexible fractional Josephson junctions (FFTJJ). The presence of collagen acted as an insulator promoted MF’s topological bound state at Majorana Zero Mode (MZM). Dissecting the differential conductance values in Z-axis, MF’s image of the spatial locations in a multiple-variable contour map can be displayed at room temperature without an external magnetic field applied.
