In this work, we analytically and numerically find the linearly dispersing Majorana fermions at k = 0, which smoothly evolve into a new branch of gapless surface Andreev bound states near the Fermi momentum. The latter is a new type of Andreev bound states resulting from both the nontrivial band structure and the odd-parity pairing symmetry.
