Moiré Modulated Lattice Strain and Thickness-Dependent Lattice Expansion in Epitaxial Ultrathin Films of PdTe${}_2$

Jacob Cook, Dorri Halbertal, Qiangsheng Lu +4

We report the epitaxial growth of PdTe${}_2$ ultrathin films on topological insulator Bi${}_2$Se${}_3$. A prominent Moiré pattern was observed in STM measurements. The Moiré periodicity…
