Experiments demonstrate coalescence angles influence phase transition in monolayer TMDs, suggesting new engineering methods.

This research aims to clarify the mechanisms behind the 1T-to-1H phase transition in monolayer TaS2.
Conducted integrated experimental and theoretical investigations.
Utilized density functional theory calculations to analyze charge asymmetry.
Employed rapid cooling techniques to manipulate phase transition rates.
Coalescence at 60° led to effective nucleation of the 1H phase.
Rapid cooling reduced the 1T-to-1H phase transition efficiency from 75% to 24%.
Large-area monolayer 1T-TaS2 of at least 180 nm × 100 nm was successfully synthesized.

Guo et al. (2026) studied this question.
