In2AB Janus Double-Layered Honeycomb Structures with Nontrivial Topology and Rashba Splitting (A, B = P, As, Sb, or Bi).

ABSTRACT: Two-dimensional (2D) systems serve as promising platforms for engineering nanoscale devices and for exploring emergent quantum phenomena. The recent experimental realization of AlSb in a double-layer honeycomb (DLHC) configuration confirms the prior theoretical predictions that traditional semiconductors are stable in DLHC configurations at the ultrathin limit and paves the way for systematic exploration of structurally robust DLHC materials. In this work, we have studied In-based InA (A = P, As, Sb, or Bi) in wurtzite, zincblende, DLHC, and AA configurations and found that all the pristine InA structures energetically prefer the DLHC structure. The Z₂ topological invariant number calculation showed that the pristine case is topologically trivial. Furthermore, using the energeti
