However, it is still a great challenge to achieve thermodynamically unfavorable twisted TMD heterostructures. Herein, WS₂/MoS₂ heterostructures with unfavorable twist angles from 0° to 100° were directly synthesized by a spatially confined liquid-precursor-assisted CVD growth. Spectroscopic analyses reveal that non-0° twisted heterostructures exhibit weakened interlayer coupling with the redshift of the Raman A_1g mode. Low-temperature photoluminescence indicates the resonance energy transfer from the MoS₂ B exciton to the WS₂ A exciton, enhancing WS₂ emission. The thermodynamically unfavorable (20°, 30°, and 90°) twisted heterostructures are found to possess much larger interfacial work function difference and longer exciton lifetimes, indicating more efficient interfacial charge transfer. This work clarifies the fundamental role of twist angle in modulating the built-in electric field and exciton dynamics of WS₂/MoS₂ heterostructures and underscores their great potential for practical optoelectronic applications. 2026-09-29T00:00:00Z Text Journal contribution 10.1021/acs.jpcc.6c04953.s001 https://figshare.com/articles/journal_contribution/Spatially_Confined_Liquid-Precursor_CVD_Enables_Direct_Growth_of_WS_sub_2_sub_MoS_sub_2_sub_Twisted_Heterostructures/34021088 CC BY-NC 4.0
