The majority of TMDs have a stable 2H phase at room temperature, WTe 2 however, only has a metastable 2H phase, with its orthorhombic 1T and 1T' being the more stable phases at ambient conditions . Despite this, we are only investigating WTe 2 in its metastable 2H phase. Hexagonal WTe 2 has unique properties compared to its orthorhombic phase which makes it particularly interesting in its use as a channel material for tunnel field-effect transistors . There is research on the interactions of these WTe 2 monolayers with bulk metals . However, this does not provide insight into the early stages of metal nucleation, but only describes whether such an interface is energetically stable. Furthermore, there is some initial work on the use of WTe 2 as a gas sensor in its hexagonal phase [58, , however this focuses only on doping of the monolayer and thus the behaviour of adsorbed metal clusters on 2H WTe 2 is still unknown. Moreover, by studying WTe 2 in its 2H phase, direct comparisons between metal adsorption on all three surfaces of the same phase can be made, due to the equivalent crystal structures.
