Description

Topological superconductors are of great interest in the study of quantum materials due to their unique properties and potential applications in the fields like quantum computation and spintronics. Pd${}_{₃}$Bi${}_{₂}$Se${}_{₂}$, a topological superconductor with a superconducting transition temperature of 0.80 K, is a promising candidate. Although it has been theoretically identified as a nontrivial topological material, direct experimental evidence is still lacking. In this work, we will present ARPES and Spin-ARPES studies on Pd${}_{₃}$Bi${}_{₂}$Se${}_{₂}$, focusing on its Fermi surface topology, surface states, and spin-polarized states at low temperatures. These insights will contribute to a deeper understanding of its electronic structure and fundamental properties, which are critical for advancing research on topological superconductors.
