TLDR
A new growth strategy employing chemical vapor deposition is developed to grow monolayer 2D alloys of Re-doped MoSe2 with show composition tunable structural phase variations which provide opportunities to study novel phenomena such as magnetism which broadens the range of their applications.Abstract:
Alloying in 2D results in the development of new, diverse, and versatile systems with prospects in bandgap engineering, catalysis, and energy storage. Tailoring structural phase transitions using alloying is a novel idea with implications in designing all 2D device architecture as the structural phases in 2D materials such as transition metal dichalcogenides are correlated with electronic phases. Here, this study develops a new growth strategy employing chemical vapor deposition to grow monolayer 2D alloys of Re-doped MoSe2 with show composition tunable structural phase variations. The compositions where the phase transition is observed agree well with the theoretical predictions for these 2D systems. It is also shown that in addition to the predicted new electronic phases, these systems also provide opportunities to study novel phenomena such as magnetism which broadens the range of their applications.read more

TL;DR: By partially oxidizingMoS2, it is found that the activity of 2H MoS2 is significantly reduced after oxidation, consistent with edge oxidation, and 1T MoS 2 remains unaffected after oxidization, suggesting that edges of the nanosheets are not the main active sites.
