Key Points

  • This research aims to determine how stacking order affects the physical properties of Janus-Ga2SeTe trilayers.
  • Evaluated the effects of stacking configurations in odd-layer systems.
  • Performed analyses on bandgap transitions and second-harmonic generation.
  • Compared results between ABC and ACB stacked trilayers.
  • Notable differences in bandgap transitions were observed between ABC and ACB stacking.
  • Second-harmonic generation efficiency varied significantly with stacking configuration.

Abstract

Stacking engineering has been investigated in even-layer and bulk Janus-Ga2SeTe, but whether odd-layer systems host unconventional physics remains unclear. In this work, we study the influence of stacking order on...
