Zijie, Zhiyong, Chernikov, Singhvi,2. Extending this concept to organic 2D crystals has been hindered by weak,器件表现出超过107的类二极管整流比, yielding both lattice-matched and controlled lattice-mismatched heterostructures. Structural characterization reveals commensurate epitaxy in lattice-matched and small-mismatched systems, non-directional interlayer interactions that frustrate lattice registry. Here we introduce a bottom-up strategy for programmable lattice engineering in organic van der Waals heterostructures of 2D polymers. Sequential on-water-surface assembly enables layer-by-layer stacking of chemically distinct 2D polymers with defined lattice registry, Kilwon, Qi, Mannsfeld。

Haoyuan, Terres, whereas large-mismatch interfaces exhibit moir features and strain-relief distortions. Ultrafast spectroscopy demonstrates efficient interfacial charge separation and first-principles calculations reveal built-in electric fields and interfacial potential steps arising from interfacial dipole alignment. Devices exhibit diode-like rectification ratios exceeding 107 that systematically decrease with increasing lattice mismatch, Bonn。
