Abstract

The weak interlayer Van Der Waals material β-Bi2Pd has recently been established as a strong topological superconductor candidate with unconventional spin-triplet pairing and Majorana zero modes at vortices. In this article, we study the topological characters and the superconducting pairing, which are still obscure in monolayer β-Bi2Pd, in light of our effective theoretical model. We find that the non-Rashba spin-orbital coupling plays a critical role in realizing and tuning various novel topological natures. In particular, the spin-triplet p-wave superconducting pairing with Majorana zero mode is revealed in monolayer β-Bi2Pd. Our studies deepen the understanding of topology and superconductivity in monolayer β-Bi2Pd and indicate it is a promising platform for achieving low-dimensional topological superconductivity.
