Among these, 1T′-ReS₂ with an ultralow symmetry stands out as a pivotal candidate. However, the fundamental scientific mechanism underlying sliding ferroelectricity in 1T′-ReS₂ remains poorly understood due to the complexity of its crystal structure. By integrating STEM, DFT calculations, and KPFM, this work resolves the correlation between AA/AB stacking and polarization in 1T′-ReS₂. PFM and STEM characterizations further reveal that the observed ferroelectric-like PFM signals originate from flexoelectric-like wrinkles rather than from intrinsic ferroelectric switching. Finally, device measurements provide evidence of sliding ferroelectricity in even-layer AB-stacked ReS₂ and demonstrate its application potential. 2026-09-30T00:00:00Z Text Journal contribution 10.1021/acs.nanolett.6c02868.s001 https://figshare.com/articles/journal_contribution/Layer_Dependent_Ferroelectricity_and_Electromechanically_Coupled_Polarization_in_Two-Dimensional_1T_-ReS_sub_2_sub_/34037314 CC BY-NC 4.0
