Topological Dirac Semimetallic Phase in Heusler-Type Li₂YZ (Y = Zn or Cd and Z = Ge, Sn, or Pb) Compounds: A First-Principles Investigation.

ABSTRACT: Topological Dirac semimetals with robust surface states have drawn significant interest in condensed matter research, as they exhibit unique transport properties. Heusler compounds have emerged as an attractive platform offering a wide range of tunability in their electronic properties, ranging from semiconductors to semimetals, along with spin-orbit coupling-induced nontrivial topological states as well as crystalline symmetry-protected band crossings. These features position them as ideal candidates for investigating topological phases, including Dirac semimetallic behavior. In this study, we performed a first-principles investigation on Heusler-type Li₂YZ (Y = Zn or Cd and Z = Ge, Sn, or Pb) compounds under two cubic space groups, F4̅3m (No. 216) and Fm3̅m (No. 225), to explo
