In Figure , we present the distances between dopant atoms and the closest oxygen atoms in O 2 , denoted as d X-O (represented by the purple bars). Upon examining the results, we observe that the pristine monolayer of MoTe 2 (referred to as Te*) exhibits the longest d X-O distance among all the substrates under investigation, measuring 3.3Å. Consequently, the primary conclusion drawn from these findings is that, regardless of the element in question, the molecule-sheet distance at the doping site experiences a reduction. It should be noted that this is true even in cases where the dopant atoms protrude from the surface, since the combined values ∆h x-T e (as shown in Figure ) and d X-O for ele- ments such as Sn or Pb-doped MoTe 2 do not exceed the molecule-sheet distance observed in the pristine sheet. Nevertheless, the extent of this change is contingent upon the specific dopant used.
