The topological properties of the systems lead to the emergence of surface states that can be observed experimentally within the angle-resolved photoemission spectroscopy measurements. Recently, the topological properties of Pb2Pd were reported. In this paper, we discuss the role of surface termination on the realized surface states. We discuss the termination dependence of the surface state for surfaces (001) and (110). We demonstrate that the Pd terminated (001) surface allows the realization of the Dirac cone-like surface state. In the case of (110), we observe clearly visible surface states with a parabolic-like dispersion relation in close vicinity of the Fermi level.
