Two-dimensional transition metal dichalcogenides (TMDs) usually exist in twoor more structural phases with different physical properties, and can berepeatedly switched between these phases via different stimuli, making thempotentially useful for memory devices. An understanding of the physics ofinterfaces between the TMDs and conventional semiconductors, or other2D-crystals forming heterogenous or homogeneous assemblies is central to theirsuccessful application in technologies. However, to date, most theoreticalworks have explored phase-change properties of isolated TMD monolayers invacuum. Using \textit{ab-initio} calculations, we show how interfacial effectsmodify the thermodynamics and kinetics of the phase transition by studyinghydrogen-induced transitions in monolayers and bilayers of MoTe$_{2}$. Thephase-change properties of MoTe$_{2}$ show substantial thickness-dependence,with the timescale for a transition in the hydrogenated bilayer being about$10^7$-times longer than that in a monolayer at room temperature. Our studyhighlights the importance of taking effects of immediate environment intoaccount when predicting properties of 2D crystals.
