Figure 6

Magnetic field dependence of the additional gap-like feature. (a) Point contact spectra of the NbSe2/16 QL Bi2Se3 heterostructure at low magnetic fields. The sample temperature is ~43 mK. Curves are shifted vertically for clarity. The black lines are BTK model fits to the experimental data. (b) The conductance difference between the experimental data and simulations vs. bias V at different magnetic fields. Curves are shifted vertically for clarity.
