| 英文摘要 | Emergent interfacial ferroelectricity has been surprisingly found in spatial inversion symmetry broken moire systems, such as rhombohedral-stacked bilayer transition metal dichalcogenides (TMDs). However, the lattice dynamics of nanoscale polarization switching and ferroelectric hysteresis remain unclear. Here we report on the observation of phonon splitting of soliton networks in bilayer MoS2 nanostructures with reconstructed moire superlattices. By tuning a perpendicular displacement field, the interval of phonon splitting exhibits a distinct hysteresis behavior, which arises from solitons disentangling and lattice viscosity. Moreover, we demonstrate a proof-of-principle moire ferroelectric tunneling junction. Our work presents a potential pathway for future moire-based nanodevices. |
